Slang term for the Corpus Spongiosum. This is the rib-like tube that runs laterally on the underside of the human penis and encases the Urethra.

It becomes more prominent and noticeable when the penis is erect.

First used on the popular comedy podcast Puke & the Gang.

A variation on the tittyfuck, one man will place his penis between a woman's breast while kneeling over her face. Another man will kneel over the woman's abdomen while facing the other man, and also place his penis between her breasts. The two men's penises will be pointing at each other and may even touch at times, like two trains passing in the Chunnel.

To Chunnel, Chunneling is the sexual practice of defecating inside a toilet roll, then inserting that toilet roll into a person, and having sex with that toilet roll whilst it's inside them.

It is commonly used around Maidstone and other areas in Kent in particular, and is named after the Channel Tunnel, because the act of chunneling looks a bit like a car going into the Channel Tunnel.
