#2 – Five Knuckle Shuffle is not what you think it is

John Cena's moves have had their names changed after WWE moved into the PG era. His finisher, FU, was renamed Attitude Adjustment while his submission move, STFU was shortened to STF with no abbreviation provided for it.
However, his signature move Five Knuckle Shuffle remained the same and is something the 16-time champion continues to use. Not many know about the origin of this but it is related to Cena's rap connection.

Five Knuckle Shuffle is slang used to describe masturbation and the meaning of this has been kept under the carpet. Not many know about this and WWE have done really well to keep this away from the kids especially.
Cena will continue using it until he retires and as it is not something that has a bad word in it, WWE might not bother changing the name.
