A fat person who farts and has no life. Always trying to kill themselves. A word me and me mates made up.
It basically means FAT FUCKER, FATTY BUM BUM, FAT FART and FAT SHIT.

Fat Shit: Look its fatty!

Fat Shit(eating chicken): Shut up or I'll belly bounce you.
Me: Aye fatty bum bum come and get a cupcake.
Fat Shit(running towards me): Where give them me now or i'll belly bounce ya!
Me: Move your head his arse is comin!!! Stupid fuckin pumpa jumpa!
