We all know that one guy who just creeps everyone out. He'll hit on anything that moves and you're usually unlucky enough to witness it. That guy is what "The Big Bang Theory" fans like to call a "Wolowitz." We usually avoid hanging out with this friend, especially if women will be anywhere in his proximity. Are you wondering if maybe you're the Wolowitz of your friend group? Here's how you can tell:

1. You're the first one to call dibs on the cute girl that walks by.

Your friends don't even try anymore. They're also not surprised.

2. You also find pretty much any excuse to take your shirt off around girls.

Yikes.

3. And on the rare occasion that you actually get a phone number, your over-the-top celebration kills it.

What's up with that weird fake turtleneck?

4. You and your best friend are a little too close.

People often assume you're dating each other, or wouldn't be surprised if you did start dating.

4. Some might say your game is . . . . interesting.

You probably get your pickup lines from the Internet or your other single friends.

5. And sometimes your efforts to woo the ladies are a little overkill.

You're a new character every time you go out.

6. Your mind is always in the gutter.

7. You're sometimes downright creepy.

Even you know how creepy you are.

8. You have strange hobbies.

Like disco rollerblading with your best friend.

9. And you're a major nerd.

10. Which sometimes becomes apparent when you're trying to flirt.

11. Let's also not forget that you still live with your mother.

Your Jewish mother who nags you incessantly.

12. BUT you're the first of your friends to get married.

Which makes no sense to anyone, but okay.

13. And you don't hesitate to rub it in your friends' faces with the latest slang you've picked up.

14. And that can make your friends a little mad.

15. But at the end of the day, you're all in this together.

16. And they wouldn't have you any other way.
