Hafa-fa-shasha
You eat the snack so fast it feels like your insides are getting fried. You have to open your mouth and chew like a wild animal just to save your guts from being charred.
I ate it like I was on fire and now I'm chewing like a wild beast.
I swallowed it so fast my insides felt like they were getting fried.
I bit into it like it was a fire trap and now I'm chewing like a savage.
