An Islamic terrorist with a suicide vest, who jumps off a tall building into a crowd, detonating the vest at the last second before impact.
The Islamikaze Pilot was killed when he hit the ground before he could detonate his vest. Fail.
Farting into your own hand, then pretending to roll it into a ball and throw it at someone. Best if executed with an exaggerated wind-up.
The bitch is getting ready to unleash a stinkball!! Duck!
