Sneaky Switch 

The act of switching the pleasuring orafice from the mouth to the anus at a glory hole. Requires a great deal of flexibility and speed to execute correctly and undetected.

I went down to the Lowe's glory hole for a blue job and the guy sneaky switched me. I had to wash off in the sink.

the sneaky bait and switch 

When someone is passed out drunk you take their underwear off and shit in them and then slip them back on the unconscious individual.When they come-to they'll think they shit themselves.Naturally,everyone involved will taunt and tease the unfortunate one as if he really had pooped his/her shorts.

While my roommate was passed out,we dis the sneaky bait and switch on him.

sneeky switch 

The female version of the Harry Houdini, where a girl tags in her friend while having sex with a man to trick him.

S totally tagged in L during her time with N. She pulled off the ultimate sneeky switch!
