GDSTB

Abbreviation for the phrase "goddamn, shit the bed!", most notably used in Tool's progressive metal song "Rosetta Stoned". This abbreviation is uttered when the speaker has suffered a shocking or traumatizing experience, and wishes to express his emotion comparable to soiling one's self.

This may also be used in surprise and jubilation.

"John, I think I ate your lunch by mistake."
"GDSTB, Bill!"
