3. To acquire, with little concern for legal forms or politesse (but not quite by stealing). “They were giving away samples, so I snarfed a bunch of them.”

4. Syn. for slurp. “This program starts by snarfing the entire database into core, then....”

5. [GEnie] To spray food or programming fluids due to laughing at the wrong moment. “I was drinking coffee, and when I read your post I snarfed all over my desk.” “If I keep reading this topic, I think I'll have to snarf-proof my computer with a keyboard condom.” [This sense appears to be widespread among mundane teenagers —ESR] The sound of snarfing is splork!.
