Can anyone here define "Ipsifendous"?

[LMNO]

The best I could do was that "Ipsi" is latin for "self" (more or less) and "fendere" means "defense"... I don't know enough Latin to know if the "ous" is an appropriate use of the root, or to whom it's addressing.

So my honest opinion is that it is some specific kind of move in combat, relating to a defensive action.
