It's potentially one of the most-used terms on a college campus. Thrown around sororities on a daily basis to describe those who spend most of their time at a fraternity. But seriously, the criteria for being a legitimate Frat Rat consist of much more than going to the same house every weekend.

Here's the list, see if you make the cut.

1. The amount of frat shirts you've collected outnumber your sorority shirts.

2. When you're wandering home from the bars/house parties you naturally end up in front of a frat.

3. Your walks of shame aren't even shameful anymore.

4. People come to you specifically to see what frat is having a party this weekend.

5. When you order pizza, you know the exact address of the fraternity house without asking.

6. You know where they hide the toilet paper.

7. You know they don't actually ever have toilet paper.

8. You use their bathroom and talk to the guy who is peeing next to you.

9. You are invited to go to the house on weekdays.

10. You have at least one fraternity composite in your possession.

11. You know the alarm code to get into their house.

12. You've gone to more than three formals in the same semester.

13. When you see apple-flavored anything, you think of the Delts.

14. Delta Chi.

15. Your name is KK.
