A slang term for a Chippewa Indian male in mid-life crisis. Usually found off the reservation fishing in waters in the Pacific Northwest.
I went to the river to stellhead but there was this cranky old Pooswa on the bank.

Sitting at the intersection this Pooswa in a black truck hit my ass.

I'm no a bigot but that Pooswa keeps checking out my girlfriend, if he doesnt back off I am going to shove a ladder up his ass.
