Powerbomb or piledriver
Piledriver in my opinion.
Any kind of piledriver.

Always thought the DDT looks like it would sting somewhat.
Definitely the leg drop
Steiner Screwdriver wouldn't hurt too bad since you'd be dead
the coco b ware GHOSTBUSTER

Ric Flair's Low blow
Boston crab bro, it's legit
Stone cold stunner - kick in the balls no can defense
Sharpshooter or Boston crab - legit but seems like a bitch to set up
Random Moniker - Always thought the DDT looks like it would sting somewhat.I've knocked someone out with a DDT breaking their nose and jaw, so it gets my vote.

if applied correctly....no can defend
