As noted, WWE sent the Young Bucks & the Bullet Club a cease and desist order, disallowing them use the “Too Sweet” hand gesture at shows and on merchandise, since WWE claims ownership. This followed the Bullet Club invading a RAW taping in California to call out Finn Balor and others. It also forced the Bucks to pull all merchandise with the copyrighted material, which they later burned.
It appears that the Club found a way around using the “Too Sweet” gesture; they’re calling it “One Sweet.”
SportsKeeda reports the gesture made its debut at ROH Global Wars: Chicago, with Kenny Omega, Cody Rhodes, The Young Bucks, Hangman Page, and Marty Scrull holding up the normal gesture with one finger up rather than two. It is probable it will make its way onto merchandise soon, though that hasn’t been confirmed.
