crab grab 

When you go behind a random girl, turn around, grab the back of her ankle with the inside of your scrunched up hand and squeeze.

It is meant to be a form of flirting.

In Brazil some may also lift the girls leg up and hold her off balance.

Go behind her and crab grab her, man!

Last night I broke my knee.. too much crabby grabby.
