Motorbating

(verb) To love looking at a car so much that you feel that you may just be able to masturbate to it.

Guy 1: what we're you doing for an hour, alone in the garage?
Guy 2: Hmm? Nothing. Just uhh... you know lookin' at my new 67' Shelby...
Guy 1: Eww. Dude. You weren't motorbating to it were you?
Guy 2: No. No! of... course not...
Guy 1: ....Why the fuck do I even hang out with you?

birthday motorboating

A practice of shaking your mouth back and forth over the lucky birthday girl's (or boy's) breasts, an equivalent amount of times to their age.

Darn, it took forever to finish Barb' birthday motorboating because she is now 88 years old. My lips are numb.
