Rocky Mountain Bow tie 

A threesome with two guys and a girl, where one guy is hitting it from behind, and the other guy is getting a blow job. The guys are erotically exfixiatating each other to reach optimal climax.

When considering possible options to liven up my Friday night, I soon found myself in the mists of a Rocky mountain bow tie with Jess and Bobby. Needless to say I've never reach a climax again unless I know it's a black tie affair.

Rocky mountain Tumbler 

Prior to going clubbing you shove at minimum four ice cubes up your ass in order to stay cool while dancing.

Tom was able to dance for hours and hours on New Year's eve because he pulled off a successful rocky mountain Tumbler.
