g-snatch
To rip something from your buddy like a thief in a movie. You shout 'g-snatch!' and pretend you're the hero of a heist.
I g-snatched my friend's drink. He looked like he just lost a bet.
She g-snatched my snack and laughed like a villain in a movie.
He g-snatched my last cookie and said 'I'm the king of the snack.'
