I hate to say it because it's one of the few moves that I go crazy over :
Slander towards the most electrifying move in sports entertainment will not be tolerated !!!!
In all seriousness, I do agree it had no business ending matches but it wasn't even its intention when the Rock started doing it. It was just a super heelish move he did on knocked out opponents , it just gained notoriety when he started getting more and more popular.
As for my answer, it has to be either the Canadian Destroyer or the C4 (Paul Burchill's flipping reverse rock bottom)
