A group of four friends so cool that they are fantastic, but so unpopular that they are worth only three people.
"Look at those guys they're such a Quadtastic trio, I wish I was that cool, but then again no one would like me."
A trio that gives a lot of comfort to you. A trio that makes you smile and gives you joy. They can probably make you laugh without even trying.
ME ; hey! who's your comfort trio?
BEST FRIEND ; it's the golden trio from harry potter!
A group of three people who break off of the main squad in rebellion in the hopes of creating a new squad
"Oh my god Natasha, Blake and Sandra are pissed at us so they are hanging out without us"
"Are they chucking an optimistic trio??"
