Snickerbating 

When you go into the shower, bed, or closet to be alone while eating a snickers bar.

My wife totally walked in on me snickerbating last night - she is way to worried about my weight.

Eating snack foods while masterbating. Particularly popular with Cheetos, which can result in orange dick, or "od".

me: how come you didn't show up at the bar last night?
you: I was too busy snackerbating and ended up with a bad case of od.
