Fousty 

A word used to describe something disgusting. Basically a mixture of mouldy, dusty, sweaty, buttcrack etc. Any disgusting word.

Guy 1: ‘Can you guys smell that?’
Guy 2: ‘*Heaves* yeah, it’s disgusting!’
Guy 3: ‘It’s so fousty! Ughhhh!’

Fousty Mop 

The complete saturation of one's hair with urine and then letting air dry fully resembliing the smell and texture of an old fousty mop.

Last night before my girl and I went out, I gave her a fousty mop. People shy'd away from us. Must have thought we were bed wetters.
