Vamoose-quite possibly derived from the Spanish "vamanos" ( "let's go") used as an exclamation or said as an order most commonly, meaning "leave!", "get out!" or, as a statement of intent, "Let's leave!".
examples: " OK you kids, I am mopping the floor-vamoose! Out!".
"You guys clear out-vamoose!"
"Uh oh, they are about to fight, let's vamoose".
