Tria.OS 

A game based of the original FE2CM game, it was originally made as a FE2CM timeline but it somehow turned into a game. The game got a lot drama due to being thought to be a FE2 rip-off but after the creator explained it's purpose to be "making maps without the script without being broken" blah blah...
Anyways it's a pretty cool FE2CM "fangame" with a small player base but with a decent community due to most of them migrated from FE2CM to this game.

Tria.OS is basically just FE2CM but better and less glitchy lol

William and Mary Triathlon 

A tradition at William and Mary in which students go streaking in the Sunken Gardens (the central quad), go swimming in the Crim Dell (an algae-filled pond), and jump over the wall of the Governor's Palace (a building in Colonial Williamsburg) at night. Truly daring students do all of this naked.

Johnny: Dude, I saw you and your girlfriend naked in the Sunken Gardens last night!
Eric: Yeah man, we were doing the William and Mary Triathlon! Right after that, we went skinny-dipping in the Crim Dell!

Trianna 

A wonderful girl with a good heart and radiant smile. She is lively and always brightens your day with her cheerful personality. When a Trianna walks into your life, she changes it for the better. She is loyal and sweet. Rumor has it that she comes from a line of princesses.

Nice Man: "Bro which girl should I take out on a date?"
Wise Man: "Why Trianna of course, who else?"

Trialism

The perception of difficult life events and misfortune as being a beneficial challenge to overcome, and therefore useful to your own personal development. The antithesis of Nihilism.

At first Sisyphus could not see any point in pushing his boulder for eternity, but then in a state of trialism, realized that there may be a meaning to his circumstance.
