An incurable disease. Symptoms occur anywhere from 1-3 days a year. It’s incurable but not too debilitating. It has an onset of irritability, weariness and homicidal thoughts. It’s usually mild enough to work through but if it comes close to reaching the homicidal stage you need to take a day to just do nothing and relax. Of course, It’s best to catch it before it reaches that stage but it typically only stays at the thought process and not the actual performing of the homicide. Although, for some reason that scientists haven’t figured out why yet, if you suffer from workitus and have a job at the post office, let’s just say you should change your career.
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.
