You eat the snack so fast it feels like your guts are being microwaved. You have to open your mouth and chew like a grumpy old man just to stop your insides from boiling.
I ate it so fast it felt like my guts were in a microwave and now I'm chewing like a grumpy old man.
I swallowed it like a kid with a candy bar and now I'm chewing like a grumpy grandpa.
I bit into it like it was a hot dog and now I'm chewing like a grumpy bear.
