Unwashed

Hey, genius, Explain bear here. Listen up! The joke is about a dude whose girlfriend is, uh, you know... but she starts choking. You'd think it's 'cause he's packin' heat, but nope! It's 'cause he's got a dirty pecker. Basic hygiene, my dude. Probably smell like blue cheese down there. You are supposed to wash it, like your momma told you, but you obviously didn't listen!
