Stole this girl's panties from our dorm's laundry room
You must feel like a total bad-ass.
This might have been impressive if you found them in your own room.
Now you just seem like some worthless stalker.
Post nudes or gtfo.
Best advice in the thread if OP actually is on friendly terms or at least antiquated with the girl (coffee/drinks/etc.) and actually is decent-looking.
If not, the girl would likely transfer to another floor/building/school.
