A drink similar to satan's main tool of destroying all self worth (the Jager Bomb), except that instead of a shot or Jagermeister dropped into a glass of Red Bull, the roles are reversed and it consists of a shot of Red Bull dropped into a glass of Jagermeister. It's what lads drink.
Jack: "If i've told you once, i've told you a million times... no one has ever died from drinking a Bomb Jager."
Jill: "...Apart from that man who died from drinking a Bomb Jager."
Jack: "God rest his soul."
