Yummiest 

Used to refer to someone extremely yummy, although it is only accurate for one person. The best yummy. Reserved for a very yummy person. Only one person though, because there can't be more than one yummiest. Very very very yummy, way too yummy to say no to. I would give up everything for the yummiest. I'd give up everything ever for some yum.

"Shelby making me go crazy so much. I can't contain myself anymore. She's literally the yummiest. I'd literally eat that shit so good 😩"
