1) A person who clearly has no idea about how car engines work, but will add up all the engine modifications he has/plans to get with preconcieved horsepower figures to show how fast his car is.
2)A person who looks like hes working on his engine, but he's really just making sure his intake didn't fall off yet and he has no idea what he is doing or what is wrong with his car.
1) (man performing ricer diagnostics) "yea, well the car has 120 hp stock, but i got a intake, muffler, and performance tuner, so its got like 160 hp now, cuz the intakes 15 hp, the mufflers 15 hp, and the chips 10.
2) yea man, theres smoke coming outta the transfuxfibulator there, i just gotta retune my muffler bearings and it should be even faster than before.
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.
