What It Is
Nate Diaz’s signature “Stockton Slap” - an open-hand slap used to taunt opponents during fights - and his shocking submission victory over Conor McGregor at UFC 196 on March 5, 2016, ending McGregor’s aura of invincibility.
Why It Matters
Diaz stepped in on 11 days’ notice and submitted the seemingly unstoppable McGregor in the second round via rear-naked choke. The upset shocked the MMA world and set up the highest-selling rematch in UFC history five months later (which McGregor won by decision).
Impact
Diaz’s trash-talking “I’m not surprised, motherfuckers” post-fight interview became legendary. The two fights generated over 3 million combined PPV buys. Diaz’s Stockton swagger and boxing skills made him a cult hero, and his rivalry with McGregor defined UFC in 2016.
