way off
This is the second-lowest step rating in the game of In The Groove, only to Miss. It is approximately equivalent to the "Boo" (pre-SN) or "Almost" (SN/SN2) in DDR and causes the life meter to drop. A dash prefixing or suffixing the rating indicates which way the player is off (-WAY OFF for early, and WAY OFF- for late.)
Several Way Offs on that cluster threatened to fail me, but luckily I pulled through and passed.
