Lava Cheese 

The super-heated cheese stuffing of any number of baked or fried foods when freshly done. Typically applied when the food is not allowed to cool for long enough.

I bit into my pizza bite right out of the microwave and the lava cheese burned the hell out of my tongue.

Lava Cheese 

When your mouth is so dehydrated that cheese becomes like lava because you cannot swallow it due to the massive amount of drugs in your system.

It's Like Lava!

Food is for suckers.
