Marth 

Someone who's a pedo, and excessively hangs out with underage girls. Is sometimes seen running around a public school or driving with loud music. Might front an image of a young teen, but in reality is an older man.

Stop texting my little sister, that's Marth'ing it.

Marth'd

A term used in fighting games with poor netcode when an attack (often associated with grabs) hits from an extended range (this name was inspired by Marth in the hit game Super Smash Bros. Melee where his grapple distance was misleading in range)

I thought I was fine up until I was Marth'd and unable to break the combo.
