A way to shadily tell someone that would would like to engage in the act of doing cocaine with them. Usually in a public place such as a bathroom stall at your favorite bar or night club.
"Yo Dewy kid lets hit up that bathroom stall and rip some fresh #3's, you down?"
Among the rarest of vaginal slang, the Arby's #3 is referring to a roast beef sandwich. Roast beef deli sandwiches are comprable, in extreme cases, to gross, worn vaginas.
Person 1: "So how'd last night go?"
Person 2: "Well, apart from having to eat that Arby's #3."
A term that misanthropists use to describe the horrible and pathetic world they inhabit. Also known as Earth. In case you didn't know, #3 corresponds to the number of the planet we are away from our sun.
Two people at a table together.
Jim: Hey Bob, why the long face? :(
Bob: I live on shitball #3, why else?
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??!!
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.
