Feinting is a standard action. To feint, make a Bluff check opposed by a Sense Motive check by your target. The target may add his base attack bonus to this Sense Motive check. If your Bluff check result exceeds your target’s Sense Motive check result, the next melee attack you make against the target does not allow him to use his Dexterity bonus to AC (if any). This attack must be made on or before your next turn.
Feinting in combat does not provoke attacks of opportunity.
