Pejorative term for college students who would rather be sociable while studying than become shut-ins. "Lounge Rats" often annoy those who dislike social interaction or getting to know the people who live near them, but give the lounge a pleasant atmosphere that can be enjoyed by all non-douchebags
Student A: Dude, why do you guys have to be such Lounge Rats?
Student B: Bish, you hatin'! Chill with us, or go back to your room and cuddle your textbook.
College students who insist on constantly taking up space in a residence hall's lounge. Lounge rats tend to partially complete homework, listen to annoying music, talk obnoxiously loud, and facebook while in the lounge. Lounge rats are uniquely annoying due to the fact that sitting in the lounge all of the time makes it awkward for everyone else that has to walk by.
Mike: Damn, Greg, I can't walk five feet down this hallway without running into a pack of lounge rats!
Greg: Yeah, they creep me out man. That Karen girl is always following me!
