Masturbarathon 

1. One of those days where you have nothing to do so you spank the monkey many/flick the bean many times!

2. When you try and see how many times you can bash the bishop/tickle the clam before it gets sore.

3. An extra long wank

"Hey, dude. What are you doing today"
"I'm having a masturbarathon, mate!"
