Cuterest

The most cute. Beyond “cute”, “cuter”, or “cutest”.
When you’re trying to win in a battle of who is cuter, using “cuterest” will instantly put you on top as the winner. Calling someone the “Cuterest” is the ultimate compliment you can give someone.

“She is the Cuterest in the whole wide world”

“I’m not the cutest, you’re the Cuterest”
