look up any word, like smh:
 
1.
You present your victim with a pudding Snack Pack and they must ingest at lightning speed, in one sitting. The "All Ages" icing.
A: Yo son you just got SNACKPACKED!!
R: What is this? What?
A: You chug it.
R: No, I'm not going to do that.
A: I bet the first guy to get iced didn't say no.
R: Alright, I'll give it a shot.
A: That's a snackpacking.
