Cutier

The internet slang term “cutier” is used to describe someone or something that is even cuter than cute. It is often used to express extreme adoration or affection towards a person, animal, or object.

Examples:

I can’t handle how adorable that kitten is, it’s cutier than any other I’ve seen!
OMG! Have you seen this video of the baby laughing? It’s the cutier thing ever!
