The Frat Boy Farters
Just an FYI:
I heard from a few bartender friends of mine that a group of guys are going around to different bars in town and farting as much as possible.
They said it's about 10-15 guys and they gave off "fraternity vibes" (polo shirts etc) and generally buy one round of beers before crop dusting the bar and leaving.
I'm not sure how exactly they're able to do this (maybe they go out to eat beforehand?) but it's really disgusting and I hope someone puts a stop to this before I encounter them out in the wild.
Good luck ...
