I think he's speaking of the Warrior Champion's spell in ToC 5m. When the bastard grab the tank and throw him behind, rolling style.
Tbh I always though they would use it as a real warrior ability, eventually. Could be fun in Arenas / BG but 100% useless in Pve. Unless you could Roll-Throwing boss too, in that case i would LOVE to roll-throw BQL (u c wat i did thar).
