Pioneer was effin the heck out of an Indian squaw.
She kept yellin WAHOO....WAHOO
So the pioneer effed her even harder. She kept on yellin. He thought she was likin it.
He finally finished and was thirsty so he went to a tavern and got a beer.
While he was sittin there he watched two Indian men playing pool...eight-ball.
One shot the eight-ball in the side pocket, exclaimed WAHOO, broke his pool stick, tossed a 5-dollar bill on the table, and stomped out of the bar.
So the pioneer was a bit perplexed...he tells the bartender that he's confused and then asks him, "what does WAHOO mean in Indian talk?".
Bartenders says, "don't you know anything?...It means WRONG HOLE".
