What Does Lockjaw Mean In Rap? (EXPLAINED)

Lockjaw is actually the street term for tetanus. Tetanus causes the body to stiffen, including the jaw. This condition prevents the mouth and jaw from moving, hence, “lockjaw.” 

In rap, lockjaw is very different and might actually be insulting to some.

When you say lockjaw, it might mean two things:

  • You are referring to a person with a New England or Northern American accent.

“My dad has a lockjaw and would always try to hide it.”

  • You might also be referring to people that mumble when talking or rapping. It seems that they have tetanus that prevents them from speaking typically. 

“I hate lockjaw rappers that are just plain lazy and unenergetic.”
