1. Invade his personal space.

You know the drill. The massive lecture hall has hundreds of seats, and you're there early. In order to really make a guy you're interested in uncomfortable, sit directly next to him.

This reassures that you are clingy and proud, because the rows and rows of empty seats in a silent, morning lecture fails to intimidate you. If you want to throw in a little extra, lean onto his arm-rest and even face your laptop towards him so he sees you shopping for that formal dress and texting your friends about not having a date.

2. Remind him that IM sports don't make him a student-athlete.

Being a student-athlete is a definitely a serious commitment.

Playing Intramural dodgeball does not. So if he asks you if you are coming to support his "big game", or makes excuses about not doing homework and other obligations because he's too focused on his team, remind him bluntly that he was not good enough to play sports in college.

This will be a low-blow to his athletic confidence, and he will surely be done with you.

3. Scream when Mr. Brightside plays at a party.

It's almost midnight, and whoever has aux at the party has already gone through this month's favorites: "Mo Bamba," "No Brainer," maybe "Jackie Chan." The DJ knows they have to play a solid throwback to get the party going, so naturally they choose "Mr. Brightside."

If you want to draw attention to yourself and let everyone know you know all of the words, scream as soon as that first note plays. Your target guy will be scared away by your "basic" favorite party song, your scream, your intensified dance moves, or a combination of all three.

4. Social media stalk him. 

To really let him know you're thinking about him, you must resort to social media.

Like all of his old Instagram pictures (especially ones with girls), poke him on Facebook, DM him on Twitter, and make sure you are snap chatting and texting at the same time at all times. Your name will appear on every social media platform, and he will fear seeing it pop up again.

To push him over the edge, follow all of him family members on social media, and comment on their pictures of him as a child.

5. Expose him on VSCO.

Make sure you really advertise that one time that he called you "baby" over text. Screenshot it and put it on VSCO, and of course add the VSCO link to your Instagram bio. Repost multiple pictures of adorable relationships, just so he's sure that's exactly what you want from him.

6. Ask for the attendance code.

If you're not ready to sit right on top of him in lecture-pester him for the attendance code every week. Let him know you can't make it because you were still getting dolled-up, and he will despise the fact that he's doing your attendance for that reason. To top it off, do better than him on the exam by studying lots while you're missing the class.

7. Pull out the headphones.

No matter where you are: the library, walking to class, the cafeteria, or the gym, utilize this method to really piss him off. Get his attention by pulling out his headphone and starting a super-enthused story.

He will be angry that you interrupted his song, and then even more heated when he becomes trapped in your story. Really be a distraction-make him late, let someone take his weights at the gym, or push his plate of food away. This certifies that what you have to say is far more important than what he's doing, and he will go crazy.

8. Send him 10 outfit options.

Whether you're just going to class or going out on the town, let him know that you look amazing in way more than one outfit.

Try on every variation of your favorites, and send them his way, even if he won't be able to tell the difference. Ask him to choose, and he will be forced to form an opinion on your jean skirt versus your black jean skirt. Then, wear the one he did not choose, and post a picture in it, just so he knows he wasted his time.

9. Wear a cheer skirt to meet the family.

Just like in the movie, he takes you to his hometown to meet everyone. To make a good impression, he tells you to dress your best. You could wear a nice sweater or dress, but why not reveal the crazy even sooner? Wear your MSU cheer skirt with your best tailgate outfit, and you will have his head in his hands 10 minutes into family dinner.

10. Replace the SAFTB flag.

This one may be the most deranged.

Remove his "SATURDAYS ARE FOR THE BOYS" flag, along with any other stray signs referring to beer or half-naked models, and in their place, hang up pictures of yourself and you two together. He will have to look at your face all of the time, and be reminded that you got away with that somehow.

But the worst part for him would probably be explaining the situation to his roommates, who didn't prefer the new decorations. When he attempts to take them down, say all the crazy things you've learned from our favorite movie, and by this point, your relationship's fate will surely be out of your hands.
