Masturbitting

The act of masturbating with ones Fitbit arm for the sole purpose of inflating their step count.

While in the midst of a Fitbit challenge a Strip Club Guru had only one chance to catch up. He went on an intense masturbitting sesh in the champagne room and ultimately finished sausage on top. The remnants of the act often resemble a Juanz Trail.

The act of eating a food so delicious that it feels as though your mouth is having an orgasm.

masturbiking 

The act of masturbating while biking by rhythmically rubbing your crotch against your bike seat. Virtually unnoticeable while in motion, this seems to be a mainly female practice.

Hey Jane, how was your commute this morning?
Great! I was masturbiking all the way up 1st Ave!
