How People Actually Use It
The term or phrase that people say when they're in a large amount of trouble. The people that are in the can on a regular basis are probably the biggest scum bags you know. Also if your friends are always in the can, than there's a good chance you'll get dragged in every once in a while.
""Lucas got caught throwing a rock through someone's window, now hes in the can." "Timmy hasn't answered his phone in a while. I think he's in the can.""
