wankometer
It's a device to measure how many wanks you are doing to the hour.
"Oy! You filthy little pervert! You were doing at least 40, and this is a built up area!"
"Sorry officer, I think my wankometer must be broken."
"OK sir put that throbbing red rod back in your trousers and we'll say no more about it."
