verb: using the pee pee powerwasher (your penis) to powerwash the toilet bowl after someone drops plops leaving a streaky shitty toilet bowl.
At the party, Dave murdered a brown snake and left it in the toilet. Dan came in after, vomited in the toilet then flushed it down. However Dave's shit streaks were stuck on the bowl. So Dan whipped out his pee pee powerwasher and did some Pee Pee Powerwashing!
