Kelera

A person who is super awesome, actually, indescribable, because they’re so cool. Words aren’t even enough to describe them and all the awesomeness that they possess.

“Hey did you meet that super cool, super funny and talented girl?”

“Oh ya she’s a total Kelera, and also definitely the favourite child in the family”
