Fanbeichui can be called 'backfist' in English. It comes from deeper down in the body than the usual backfist. It is thrown out from the back. One of our lineage members is known for knocking out a thief twice his size with this technique.
It is unique in that it uses a fist. It is used along with stepping to apply a technique when it seems like the back is turned to the opponent. You turn your back a little, which changes the situation, so you attack when you appear to be losing.
