Flathead 

A disparaging label for someone that believes the Earth is flat.

The flathead will argue with you about whether Antarctica is a continent, he thinks the world looks like the map in the United Nations logo, where the Antarctic forms a ring around the flat Earth.

one who insists that the Apple iPad's lack of support for Adobe Flash dooms it to failure.

I just heard a guy say he won't even consider an iPad because it lacks Flash support. What a Flashtard!

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.

Flathead 

A term used to describe a person who lives "on the edge" and is very wild. The term came from Michael Flatley, who invented the Riverdance Irish Dance ensemble. "Flathead" was used to describe his fans who were very wild and crazy and the term grew from there...

Bill: This flathead I went out with last night was just too wild for my taste...
