Pro-wrestling martial arts.
Basically a two-step attack. First hit you do on a monster is a basic grab attack, then next attack on same monster could be a suplex, piledriver, or powerbomb. Said attack can do massive damage.
...however, since most opponents are pretty much unwilling to be lifted up for a wrestling move, at most a survivor with decent strength can only successfully lift up zombie children, dogs, and a crawling zombie.
