A term used to accompany the theft of someone's
stuff. Not burglary style, but while they are there and not paying attention. Usually for stealing food.
Also a general term of enjoyment, for getting away with
something or getting out of a
jam.
Group of friends at lunch:

5 mins later
A: *Takes
fry and eats* "Snatchies!"
or
"Dude, I'm glad that
cop was asleep when we blew past him at 90!"
"Yeah especially 'cuz you're not allowed to drive after nine and we're drunk!"
"SNATCHIES!"
