It stands for a White Man Power Run. It is used for people that don't have extreme skills in sports but have the determination to run through everyone in their way without fouling or being fouled by anyone. It is one of the most beastly moves in all of sports. It is pronounced normally as wmpr or in a beastly/screaming way of WHITE MAN POWER RUN!
I'm going on a wmpr this game!
