STFU

The submission finishing move of John Cena. This hold is known in professional wrestling as the Stepover Toehold Sleeper (STS) and innovated by Masahiro Chono. The wrestler performs a stepover toehold and wraps his arm around the neck of the opponent as in a sleeper hold.

John Cena made Batista tap out when he applied the STFU.
