ICBINB! 

ICBINB!
noun

1. Abbreviation for a margarine (fake-butter) product, I Can't Believe It's Not Butter!. The stupidest abbreviation (nobody can decipher what the hell ICBINB is unless they're told) for the stupidest product (if you're worried about the calories in butter, don't eat fake butter, just stop eating the damn butter!) in the world.

That dude is spreading ICBINB! onto his baked potato crisp and downing a six-pack of diet Coke...

Flavoured ICBINB! spray? That's gotta be the most ingenious invention since matzo...you can eat it like those sour spray candy things or use it as cologne!
