oldschool cartoon about a couple of wordmonk/words who live at number 3 tree st and eat bananas.

The contents of a well-used but badly flushed lavatory, the bangers (sausages) being the turds and the mash (mashed potato) being the bog roll.

Made from the word "banging", bangers and mash is simply one step further. To describe something that is better then good we use excellent, to describe someone more cool then cool we use ice cold and to describe someone or something more banging then banging we use bangers and mash.

A sexual act. The girl has a mouth full of mashed potatoes. The girl gives the guy a blow job..... with her mouth full of mashed potatoes.

An outstanding and indie-rock sounding song written and recorded by Radiohead from the "In Rainbows" album. The song features Thom Yorke on drums, while he sings at the same time.

When an arguement gets violent.
Usually a beating of some kind, the mash being the victim and the bangers being their attackers.
It doesn't literally make sense, since sausages don't usually beat down on mashed potato, but whatever.

Human excrement deposited onto train tracks when passengers flush the train toilet while the train is at the station.

A pile of moist toilet paper (resembling mashed potatoes) with a deposit of human excrement (resembling a sausage) protruding from this.
