flimsy low hand

When a guy hooks the the elastic band of his under pants with his thumb pulling them down to taking a piss. The thumb then slips off the waste band and <smack> right on the dick.

I gave myself a flimsy low hand last night. I was so drunk my thumb slipped right off the elastic and nailed me right on dick...

flimsy low-hand 

A REALLY good hand job. Often quick and to the point resulting in an unexpected mess.

That emo chick that works at Starbucks gave me the flimsy low-hand last night in the parking lot. It was amazing....
