Gretch 

to violently sneak.

To go or move in a quiet, stealthy way while having some sort of a violent, destructive motive.

That fucking oven door gretched up on my hand!

Hey man, stop gretching up on me!

So, I was playing paintball and had a sweet sniping spot. Then out of no where Chris gretched up on me.
