Haviing anal sex, using a condom covered in BenGay or Icy Hot, with a former partner that has cheated on you. After ejaculation you slap them in the face with the condom, and tell them to leave.
My Ex-girlfriend came back the other night, so i gave her the ring of fire, and told that bitch to leave.
Five friends sit in a circle with a handle of vodka or similar hard alcohol. The song "Ring of Fire" by Johnny Cash is cued up to play. As the song plays, the bottle is passed from person to person, each taking huge swigs. The goal is to be finished with the handle by the time the song is over. The song is 2:30.
