A clever phrase to let chums know how thouroughly annoyed you are with them at any given moment. Most effective when cleverly hidden in an unexpected place, in a seemingly unrelated sentence. (See example below.)
Chum: Man, did you watch that special they had on dateline last night? The one about Lynyrd Skynyrd? That was really cool.
You: Yeah, it was prettysweet. Almost as cool as SHUT THE HELL UP!
A: Shut the hell up!
B: What?
A: Shut it up, quick! Before it sucks us into the void that it is!
B: Oh, you meant that gaping portal to hell in my bathroom. Yeah, uh......that's a toilet.
