It does appear to be a combination of wrestling techniques, though, what with Lynette using Muscle Buster on Perrine on top, and Yoshika doing some weird piledriver on Mio.
It's called "Muscle Docking", a combination of Muscle Buster and Muscle Driver. Done in Kinnikuman. King and Marduk also did this in Tekken 5 as Namco's tribute to Kinnikuman (though Marduk only did a regular piledriver, Armor King gains the Muscle Driver in DR).
