When someone has glossed/glazed over eyes and looks messed up possibly from sinus problems or being stoned.
"Man that dude's got some hoozy eyes!"
When you take a shit and it goes messy, wiping takes forever and it looks like melted chocolate smelling of shit.
"I'm gonna be a while in here, I've got a choccy bum!"
When you know you have a massive shit brewing and its going to be huge!
"I've gotta go to toilet I've an egg up my bum!"
