Grundle Bomber

1)The act of landing an extremely devastating Martial arts blow to another person's Grundle, through one of several methods:
1a)Launching a person into the air, through a well-placed kick, or uppercut, and then positioning yourself underneath them, squatting, sitting or in crab-walk position, with one knee fixed firmly upright, so that the recipient lands their Grundle directly on your knee.
1b)(also known as "Grundle Bomber - Jackhammer style") A grappling move, in which the one who performs the Grundle Bomber launches into the air with the recipient, turns them upside down, holds the recipient's Ankles, and places their foot(s) or knee(s) on the person's Grundle. This will cause them to land perpindicular to the ground on their head, while the one who is giving the Grundle Bomber lands with their foot(s) or knee(s) on the recipient's grundle, usually causing the recipient to split in half.

2)Placing an explosive device in the pants or underwear of the recipient, in the grundle area, and causing it to detonate while they are being worn. Can be used in conjunction with definition 1.

3)Using one's Grundle to physically attack, As seen in the Jumping/butt-slam move in the popular video game "Street Fighter 2" by E. Honda.
