The act of jacking off next to some one other than a mate. Ex: your mom, your sister, your friends, your teachers etc. You can be sneaky under covers, under desks, etc. This term originated from a young middle school boy who got sneaky with it under a blanket on one side of the couch while his mother was on the other end of the couch. She had no clue at all.
I got sneaky sammy with it in class yesterday when my teacher bent over and i saw her cleavage.
