frog punch 

An extremely powerful offensive maneuver only used by the hardest of core. A special punch delivered by extending the second knuckle of the middle finger outward to a point, while clenching the fist. Aim for the throat for devastating results the likes of which your opponent, punk-assed bitch that he/she is, shall never forget.

Don't fuck with me, Victoria, or I'll frog punch your titts.
