Blubbyupski 

The act of squeezing the back of someone's leg, specifically the gracilis and biceps femoris muscles, and squeezing firmly. When carried out properly, the target (victim) will typically collapse with a scream and violently convulse to escape the grasp.

I was sitting at the dinner table, minding my own business, when all of a sudden my brother gave me blubbyupski.
