nacho shiv - A nacho fragment so mean it doesn't just bite you, it shoves

A nacho fragment so mean it doesn't just bite you, it shoves its whole nacho soul into your gums.

My gums are screaming. I think I got a nacho shiv in my mouth.

That nacho shiv was like a tiny revenge mission.

I bit into a nacho and it was like a surprise attack from the inside.
