#4 Leg slaps are perfectly legal in AEW
AEW would take two distinct jibes at WWE when the latter brought in a rule that banned wrestlers from slapping their legs while performing kicks. Traditionally the wrestlers use the sequence of slapping one's leg to emphasize the kick’s sound effect.
Wrestlers who are caught not following the ban will be fined. Backstage reports and photos have highlighted the prevalence of several such notices of "Do Not Slap Leg When Kicking" signs in WWE.
In a storyline over in AEW, Papa Buck would be viciously attacked backstage by Jericho & MJF to send the World Tag Team Champions, the Young Bucks, a message.
A week later, Don Callis would interrupt the Bucks' backstage interview to offer his condolences towards their father. As a generous gesture, Callis would offer a recovery gift for the duo's father.
The gift was be a t-shirt that said, “DO NOT SLAP LEG WHEN KICKING." The shirt was thrown aside by Matt Jackson, but their intended shot at WWE did not go unnoticed. Furthermore, Matt Hardy and the Bucks had already joked about the ban on leg slapping in a Being the Elite episode before this televised event.
