Snap Kick feat from the Book of Nine Swords says,
Do you think the feat can be used when a character is charging? How about when a character make an attack of opportunity?
When you make a melee attack with one or more melee weapons (including a standard attack, full attack, or even a strike maneuver), you can make an additional attack at your highest attack bonus. This attack is an unarmed attack that deals damage equal to your base unarmed attack damage + 1/2 your Str bonus. You take a -2 penalty on all attack rolls you make this round.
