Used in situations of absolute brilliance (see also danson) in tribute to the amazing side scrolling, free to download game - jellycar (jellocar american).
1: An incredibly slow elevator that is in fact a giant jellyfish. The first known jellyvator appeared in World of Warcraft's five-man dungeon, Throne of Tides.
Man - have you played Throne of Tides yet? The jellyvator takes like five minutes a round trip! Good thing they put in a teleporter.
