I lived with 3 guys my second year of college in a townhouse we rented. OMG talk about messy and gross . . . Yeah the only girl ended up doing all the cleaning. The one guy deep fried EVERYTHING, in a little pot of oil, just one thing that sticks out in my mind.
The BIGGEST mess was the guy in thier fraternity who would **always** drink way too much beer and somehow end up at our place, upstairs bathroom. I will admit he got some barf in the toilet, or at least on it. In the sink, in the bath, in the SCREEN of the window in the shower. Ok I had to clean it up the first time, the next weekend he did it I guess he felt bad and tried to wipe up a little . . with paper towel, which plugged and overflowed the toilet.
He flushed his glasses down the toilet one of the times too.
One guy would put his cigarette butts in the beer bottle when he was *almost* finished drinking it. OOHH that was NASTY to take back to the store and sort for deposit LOL
