wanderbating 

To wander whilst masterbating. Frequently performed by those who get distracted easily and need a change of scenery. Painfully awkward for room mates, houseguests, parents, etc.

wankerbatting 

When you spank your monkey with such force and grip it makes it burn when you pee.

"It burns when I pee."
"Stop wankerbatting then!"
