The social indoctrination to the bar scene that occurs on or immediately after one's twenty-first birthday. Typically, the guest of honor on a "21 run" is forced to consume copious amounts of alcohol in a short amount of time. This often results in illness, and, in extreme cases, loss of consciousness. The prototypical "21 run" occurs from 12:01 AM until 2:00 AM on the participant's birthday, this time being the first at which said individual is legally eligible to consume alcohol.
A man's friends who are already twenty-one pick him up and take him to the bars one minute after he turns 21, at 12:01 AM on a "21 run."

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.
