flophouse 

Any house/apartment/frat house/trailer/etc. which is used for individuals to crash (sleep, chill, hang out, lurk, etc.) for a period of time. In order to "crash", one must not actually live there (e.g. have their name on the lease, own said flophouse, etc.). Flophouses are typically used by college students, drug addicts, transients, vagrants, or other unsavory characters.

A flophouse may also be the home owned by the parents of a college student, who after being away at college, wishes to live as if he/she is still at college (e.g. staying out all night, returning just to crash at mom and dad's house, then leaving again), rather than conforming to the pre-college rules.
Example #1
Dude: (Talking to someone passed out face first on the floor of his college apartment) Hey man, who the hell are you? What do you think this is, a flophouse??

Bro: Sorry dude, I must have passed out for a minute.

Example #2
Mom: Where have you BEEN for the last three days? You come home just to sleep?? What do you think this is, a flophouse??!!

Son: What's your problem? I'm an adult now!

Hate Sink 

A person you hate intensely not because they deserve such hatred but because they serve as a focus for your general hatred. A healthy way to dispense with excess animosity.
Jake's not really that big an asshole. He just serves as my hate sink.

A toe rag was originally a foot wrapping used, since mediaeval times up until the mid-nineteenth century, to protect the foot from chafing by boots or shoes. As these were, quite literally, rags they weren’t usually washed, and so with use they became very smelly until they were thrown away. Because of the similarity in smell, toe rag also became the name applied to dried, salted cod or other things with a strong, unpleasant, fishy smell. It didn’t take that long before the name was applied to someone who was an obnoxious, unpleasant OIC.
1 “Socks! Those aren’t socks you smelly git, they’re toe rags!”
2 “What have you been cooking? Smells like toe rag!”
3 “I can smell ‘er fanny from ‘ere, proper toe rag.”
4 That Heale Malcolm is a right toe rag.
