An acronym for "Lets Get Fucked Up And Die"
Popularized by Motion City Soundtrack's song L.G. Fuad.
Usually an expression of exasperation, hopelessness, or annoyance.
Staci: Ugh. We have 3 final exams tomorrow.
"Let's get fucked up and die.
I'm speaking figuratively, of course.
Like the last time that I committed suicide.. social suicide."
