IBH is an acronym for "Itchy Butt Hole". It is used in reference to having an itchy anus from lack of hygiene or anal leakage.
Man I've got a bad case of IBH going on right now, I can't sit still. I guess I need to wipe my ass better.
Excuse me, do you guys sell bidets here? I keep having horrible IBH and need to wash my ass in the sink after every time I have sticky shit that's hard to wipe off. A bidet would make my life easier.
Dude, why are you walking funny? Looks like you got IBH. You should learn to wipe your ass better.
Thinking to one's self: Geesh I need to stop shoving things up my ass it's stretching it out too much causing anal leakage. It's making my IBH worse.
