The act of taking your strong arm and feeding it under an unsuspecting friend's legs as he stands and lifting him up by his grundle. This will cause extreme pain of the marble sack and or loss of baby makin mojo.

When two men rub their grundles together to get off; this act is much like when two women scissor each other.

Grundle is another word for chad: the region between the balls and the arse-hole; can be an erogenous zone for some.

'Eww! He had a shitty chad.'
When you measure your dick, you don't start at the arse-hole and include the chad; you risk getting shit on your measuring tape.
