Rusty Nutcracking Trombone
This is a sexual act in which your partner gives you a rim job and a reach around at the same time Rusty Trombone. However, in this variation your partner removes their false teeth and clamp down on your testicles as hard as possible.
I thought Sharon wanted to make up for all those years of treating me like crap by giving me a Rusty Trombone for my 40th birthday. But she Charlie Browned me by pulling a Rusty Nutcracking Trombone on my already sore balls.
