Fartbarn

Fartbarn. The rectal cavity, a place where farts are stored before being dispersed to the local atmosphere.
A large airy space that stinks of shit.

Shut it you fucking fartbarn.
Your missus has breath like a fartbarn.
Less of it you turdgobbling fartbarn.
Fuck staying in that hotel it's a proper fucking fartbarn.
Arse Shitty smell
