Setting

Setting up or to Set up a public but anonymous meeting for sex, Setters usually wear a mask and hood/hat, they don't generally speak in person and the participant receiving waits leaning/bent forward over a wall or fence (Somewhere out of public eye) etc and puts something of an agreed colour hanging out of their back pocket. This allows the other person to simply walk up behind them and initiate sexual contact.
The setter is the top and the spark is the bottom.

Participants can be M/M, M/F, T/M, T/F F/F. (OF LEGAL AGE!) A very UK silent practice.

I'm going Setting tonight, Do you fancy Setting or "Do you Set?" Setter is the top and Spark is the bottom.

De-Kegging

De-Kegging, The removal of the pants and underwear in one swift movement by a third party.

This practice was brought about in British Prisons, Boarding Schools and Borstals around the 1970's, this involves a person sneaking up behind another person (Typically boys) and grabbing their pants waistline.

This is followed by a swift downwards pull taking the victims pants and underwear to their ankles.

Masked as a way to humiliate the person publicly, this is actually a homosexual based act which allows the first person to see the victims penis & size whilst playing the "i did it for a laugh" card, thus covering the first persons intended sexuality.

Jason "Humiliated" by De-Kegging him in front of everyone.
