If you do not know what a reddit UHC or what UHC is, please read ahead. If you do know then don't.
UHC: A gamemode made by the mindcrackers. Health does not regenerate and it's a fight to the death! Golden apples heal and so do potions.
To2 or To4 or To3 or something = Teams Of (NUMBER) and if it has an r infront of it, it is randomly chosen teams. The chance of you getting to team with your friends are slim and for random teams teamspeak is required.
Public UHC's hosted by random people on the subreddit mainly about UHC
