Long acronyms I have known

[flexagon]

While washing my face I found myself trying to think of all the really long acronyms I know. I thought of these:

WALSTIB

TANSTAAFL

ROTFLMAO

SOHCAHTOA

WALSTIB -- What a long, strange trip it's been. (Grateful Dead lyrics)
TANSTAAFL -- There ain't no such thing as a free lunch
ROTFLMAO -- Rolling on the floor laughing my ass off
SOHCAHTOA (the Indian chief) -- Sine = opposite / hypotenuse, cosine = adjacent / hypotenuse, tangent = opposite / adjacent.
Do you know any more that are good?

I could've also mentioned DTMFA, which is a Dan Savage thing: dump the motherfucker already!
