A successful Falcon Punch requires focusing mass amounts of pure pwn into one's fist, before hitting the target as hard as fucking possible - hopefully dislodging several vital organs along the way. The Falcon Punch is most often used to end the untimely pregnancy of a loved one in a humane manner, especially if the loved one happens to be under the age of sixteen. It is also used often to destroy idiots that are killing the internets, through a primitive, but effective text form.
Carrying out an IRL Falcon Punch is a simple procedure done in a few steps:
1. Pull fist back screaming: FAAAAAALLLCCCOOOOOOOOOOOOON
2. Thrust fist forward whilst also screaming: PAUUUUUUNNNCCCCH
Warning: Expect arm to catch fire if done correctly.
