Can a Dirty Fighter (orc arg archetype) use dirty trick as an AoO?

[Bertious]

Specifically a level 9 Dirty Fighter gets the ability to use dirty trick as a normal attack so can he AoO with it and if so does the ability to blind as an AoO make him an impressive "Tank"?

Yes, it seems like he can do a dirty trick as an AoO.

The wording on it is a bit strange, but yea, that should work.
