Evander handypalm, (n). A type of masturbation using a vinyl boxing glove and some KY to stroke your meat till you bust one out through the grasp hole, hopefully onto someplace it's had to wipe off. Done best while sweating after a workout in a locker room.
Tibone: You ever try the evander handypalm?
Ronnie: The what?
Tibone: That's when you beat off in a boxing glove.
