Butt Jointing also known as ‘Spigoting’ when scaffolder engages in the sexual act of joining two Brasses (prostitutes) together arsehole to arsehole using a spigot fitting.
‘Went out strait after work with the boys on the Wandsworth job and got on the Stella and packet last night ended up in a Brass house (Brothel), couldn’t get a hard on so I ended up Butt Jointing two Brasses (prostitutes) together and talked shit to them while watching them stagger about like a human crab slapping my limp meat about’
