When a female rubs her face in a back-and-forth motion against a mans scruffy beard because she loves the feeling. So named, because of a resemblance to the act of "motor boating" a female's breasts.
I just saw Seth and his amazing facial hair; clearly, I couldn't help but spend some time motorbearding him!

The insertion of a person's face into a man's beard followed by a back and forth motion. May also be accompanied by the standard motorboat sound.
Man, we were just sitting there and suddenly she jammed her face in my beard and started making motorboat sounds.
Dude, you totally got motorbearded!
