masher 

A person who plays computer games (especially fighting games) with the use of his/her lightning fast reflex of randomly pushing/bashing/smashing and yanking each and every button (including the buttons of the player next to him/her) on the contoller/arcade without any idea what the hell they're doing.

Arcade Newbies play by being a masher.

masher 

A man who exudes total confidence in all situations. A masher will back down to no man, and often emerges decidedly victorious from any physical confrontation or daring act. As a result of the mashers extreme confidence, a masher is no stranger to having his way with many an attractive woman.

Though he's a raging anti-semite, Mel Gibson does have littany of masher roles to complement his body of work

Masher 

A great guy, generally ginger who likes the odd tipple here and there.

His favourite colour is almost always orange.

He's an awesome friend that's the life and soul of the party and he will always be there for you when you need him.

He has a great booty that he ain't afraid to shake!

Can you see him dancing, I mean REALLY dancing? That guy's clearly a Masher

Masha is defined as an awesome guy with a great booty that don't need no explaining
