The act of Nigheisting. To steal something to a lesser degree, claiming it by proclaiming "Nigheist!" Also, to take someone's place in an order, advancing oneself to a previous spot in a roster or line by proclaiming "Nigheist" as the person who claimed the spot left or wasn't paying attention.
Seeing his friend crawl off to the bathroom, the sly devil creeped over to the Guitar Hero Guitar, yelling "NIGHEIST!" as he started to play Sunshine of your Love.
