Toothy bum

Inserting toothpaste inside your anus so your arse smells minty and fresh.

My arsehole stinks! Have you got any Colgate? I fancy having a toothy bum today.

Sea mine

When a male or female starts masturbating in the ocean.

Example 1: You guys go and enjoy your surfing. I'm just going to stay here and sea mine.

Example 2: I apologise, but this beach is closed to the public as there are too many sea mines.
