skinflapping 

A well thought out synonymous for jerkin the gerkin.

Dude my gf's hot mom totally turned me on so I was forced to skinflap it in the bathroom.

I'm totally skinflapping it since my gf found the pornstash.

skilapping

When two or more people join together in a circle and fart on eachother while yelling "skilap"
