Where did all of these "couple teams" come from?

Well,I Actully Came Up with 'Team Random'.
I Don't Who Came Up with the Other Ones.

যেভাবে খুশী actually. So, if i not mistaken, I made "Obivious,Fabulous,Marvelous"
Which I follow a simple recipe : Show that contain 3 guys would make a team couple
For example : GG - Chuck,Nate,Dan
আপনি just have to get Chuck to be with someone,Nate to be with someone, and Dan to be with someone.
Cherry,Nair,Derena In that আপনি follow a simple rule, NO BRO-SIS AND NO MATCH.
Chenny,Nenny,Danessa Jenny could only be with one person in a triangle.

The name we just make it up, For people to start calling it, আপনি need to make a pick, অথবা a spot.
Hope I helped you.
Thanks

P/S now i'm actually পাঠ করা your question.
So like i said, প্রদর্শনী that contain three guys normaly make a Team.
And all three guys have to be with someone.
It's clear that THE ENDGAME was made before Trifecta. Because they happen first.
Now Trifecta is ..kinda আরো popular, obviously because they happen after so...
And i think Endgame was the first group couple ever (saw somewhere on ইউটিউব ) yay !
