Split Punch (3.5e Maneuver)

You do the split before hitting your opponent where it really hurt, between the legs.

Upon initiating this maneuver you make yourself prone and make a single unarmed strike (with the associated penalties of being prone). If you hit you deal an additional 5d6 nonlethal damage and make the struck creature dazed for 1 round then nauseated for 2 round. A successful fortitude save leave the struck creature sickened for 1 round.

Creatures with no discernible anatomy and immune to pain are immune to the extra damage and effect dealt by this maneuver but not the regular unarmed strike damage.
