The Temporal Fist is a long forgotten technique of the Furons that is used to pretty much throw a lot of crap around at once. To perform this move simply freeze time (B), and then PK Throw something (Hold LT then press Y). When you first learn this move you should be able to get nearly half the throws required. Afterwards just go outside and start Temporal Fisting (that was poor wording on my part) everything in sight. Remeber that the achievement is for USING the temporal fist, so you can throw ANYTHING: people, cars, rocks, hot dog carts, etc.
