Since their reunion on AEW: Dynamite, Kenny Omega, The Young Bucks and The Good Brothers have started to use the Too Sweet gesture again, calling back to their Bullet Club days.

The Too Sweet gesture has been used in professional wrestling going back to the 1990s. It was popularised by The Kliq and the nWo and later returned to prominence after it was adopted by Bullet Club.
All Elite Wrestling could have some trouble trying to trademark the term, though. Pro Wrestling Tees' parent company Creative Ventures, Inc. tried to trademark "Too Sweet" in 2017, but the application was refused and later abandoned in February 2019.
In regards to WWE, the company filed to trademark the Too Sweet hand gesture in 2015 but the application was abandoned in 2017.
