Being Sent to The Shadow Realm
A term typically used while playing fighting/platformer games. This entails being hit off-stage and losing a stock. Unlike "Being Sent to Brazil", this occurrence involves the fighter being sent down at a 90° angle to the floor. The most common occurrence of this is in the Super Smash Bros. franchise, in which one fighter can strike the other using a certain move that spikes the opponent straight down (this is referred to as a "meteor smash" by the creators of the game).
"There's nothing more embarrassing than being sent to The Shadow Realm after talking smack to your opponent, trust me it's a nasty experience."
