Fist bump 

When 2 people are bent over standing with their butt cheeks touching and, simultaneously, fake sneeze until their sphincters kiss.

Person 1: Aw man, I'm going to have to stick to soft foods for awhile.

Person 2: Why's that?

Person 1: Because we were fist bumping until I gave myself a hemmorrhoid.
