Roommates are part of the college experience. Whether you live in the dorms or an apartment, you’ve probably had one.  A good roommate can make your college days a blast — but not everyone is so fortunate. Here’s a list of the ten worst kinds of roommates.

10. The One Who Leaves Hair Everywhere

Nobody likes to start the morning by stepping into a shower full of hair. Unfortunately, seemingly everyone has had that roommate who sheds like a dog and doesn’t understand the concept of cleaning.

9. The Uptight One

Everybody needs to buckle down for an intense study session every once and a while. In those cases, it’s okay to ask the roommates to keep it down. What’s not okay is a chronic case up uptightness.

8. The One With Illegal Pets

Pets aren’t allowed in the dorms or most apartment complexes. Yet there’s always someone harboring cat contraband.

7. The One with Loud Music

Again, blasting music is okay sometimes — just don’t keep everyone in the surrounding area awake until 5 a.m. on a Tuesday night.

6. The Really Rich One

There’s always that one roommate with thousands on their LionCash and even more in the bank. They just never seem to understand why you can’t drop $2000 on Spring Break.

5. The Drug Dealer

Strange people visiting at odd hours? Strange smells emanating from the bedroom? Always running out of plastic bags? Your roommate is a drug dealer.

4. The Lazy One

“I don’t have to do dishes, because I don’t even use any.” Lies.

3. The Crazy One

The Amanda Bynes of roommates. Their life centers around drama. They constantly start fights, and always seem to be crying. Avoid the crazy roommate at all costs.

2. The Extreme Partier

This roommate needs constant babysitting after those long nights of partying, unless you want vomit all over the living room or a chair over the balcony.

1. The Mooch

The ultimate source of annoyance. They constantly ask to borrow money and never pay it back. They will always drink your booze. They will always take your clothes without asking. Worst of all — they will eat your food.
