A combination of the word "sneak" and "knuckle". To be punched epically (usually in the face) without any warning whatsoever.
Mary is a total ninja. She snuckled over 57 people in a 30 minute period and was never caught.

Kevin thought he could escape, but Alex was far too quick for him and snuckled him in the face.

Daniel - "I'm going to snuckle you!"
Matt - "It's not a snuckle now that you told me. Dumbass."
