What is Flathand?

Flathand is the process of masturbating (male) when a subject arouses themselves by using an open palm to the underside of their penis instead of the traditional closed grip, to the point of ejaculation
Hank is such a idiot, he is probably the type of guy who flathands himself.
I am so tired, I can't even grip my dick, but who cares, I can just flathand myself.
