A prank where you quickly close someone's laptop when they're not expecting it or in the middle of working with it. Ideally the laptop is set to hibernate or shut down when the lid is closed so they have to then reboot their computer.
Best practice is to shout 'Awww, lapslap!' when lapslapping someone.
"Fuck, I just got lapslapped and my computer takes ages to restart... and I didn't save my essay."
Lazy + Sloppy. You'relazy so it makes you sloppy. It is also strongly related with a lack of professionalism.
When you receive an email from a university, and the subject says "Your Student's Application is Now Complete" and the email is about a piece of your application being *incomplete*. The admissions offer is demonstrating laysloperism.
When you tell your students that topic 7 will not be on the test, and then when you take the test, you see that topic 7 has been put on the test by the same teacher which stated that it would not be on the test. The teacher is demonstrating laysloperism.
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??!!
