Telling someone to seriously fuck off. Don't just go suck a dick, but suck a fat dick. Especially if it's a weak or lame thing that the guy did.

-- Hey man, I took some money off your dresser. Then a bunch of dudes at the bar talked me into buying rounds. I'll pay you back though, as soon as I get my next paycheck.

-- Dude, go suck a fat one!
