Faygo
A straight up motherfuckin' miracle, drank by tha one and only GAMZEE MAKARA.

It also has a connection to Juggalos and The Insane Clown Posse but nobody gives two shits about them.
"BRO, I'M SO INTO CLOWNS OF A GRIM PERSUASION WHICH MAY NOT BE IN FULL POSSESSION OF THEIR MENTAL FACULTIES!"
"OH HOLY SHIT, DO YOU LOVE FAYGO AS WELL!?"
"FUCK YEAH"
