Top Dweller
Often used at parties when the host is disliked somewhat, the top dweller is when someone, instead of using the toilet as normal, takes the lid off the cistern and shits in there. This results in shit particles flooding the toilet every time it is flushed. It can last for weeks on end, depending on the quality of the shit
Bro, that cunt tried to kick me out, so I left a top dweller in his loo. His mum will be cleaning that thing for weeks
