Something that's both cuckoo bananas and a little unfortunate.
"Yeah last night was crazy! Pretty sure I threw my shoes out of a car window though."
"Haha wow, that's shitty bananas."
When something happens and you want to talk about it, but can't, so you look at your friend and they just KNOW.
*Tom foolery goes down in a crowded room*
So you lock eyes with your buddy and eye vent :
"Can you believe that?"
"I know right!?"
"Shut the fuck up, goddamn."
Similar to STFU, but with more gusto. Most efficient when used while yelling.
You: *trying to tell story*
Friends: *talking over you*
You: "STFUGD!"
Friends: *stunned in silence*
You: "now as I was saying.."
