Popularized in the 2018 novel "Death of a Guardsman", when the protagonist demands that his apprentice "gobble his coggle", meaning he wants to be deepthroated and gagged on. To have one's coggle gobbled basically involves receiving a really awesome blowjob that produces a full-body high that can't be replicated in unprotected sex. This is the best thing that can happen to a person. In fact, I'm getting my coggle gobbled right now. Ooooh yeah. OOOOOOOOOOOOH yeeeeeeeh.

*eggplant*

The act of extreme masturbation. You must "knock one out" whilst in close proximity to any of the following; Your mum, a nun, your boss, a member of parliament, George Michael. A person with capabilities to act upon catching you mid self-abuse obvisouly ups the ante. Ejaculation must be reached before your danger wank target comes (no pun intended) to investigate. The higher the chances of being discovered with one's pants down, pulling one's war face is obviously where the danger comes from. The more danger involved the harder (or softer) it is to complete the task in hand (snigger). The more dangerous the better. The chance of being arrested, pummeled by an angry father or having your hand severed by an arab's sabre means that you are a pro "Danger wanker."
