When someone jumps onto someone to injure them (or sometimes killing them)
The personwill normally be laden on the victim with there feet, but doesn’t necessarily need to be.
To pronounce, it is simply Mario with ‘ed’ (as in jumped) at the end
“Steve jumps off the ledge and marioed the robber below.”
“He just got Marioed”
As in the computer game on nintendo. The character runs over things. So if you were to jump on/over and run over something, your would be said to be mario'ing the item.
"I marioed that car" when your would runover it from front to back!
A person pretending to be something they aren't, or an impostor. This is inferred because of the old alien movies where alien pods appear on earth and the "pod people" dispose of the humans and slowly reproduce the bodies, pretending to be humans.
The pod person was pretending to be my father, but I knew that he was an alien when he acted differently than my father ever would have.
