nacho helmet

A baseball helmet without ear protection. It was reverse-named as such because restaurants would have promotions serving nachos in toy baseball helmets that looked similar. Reggie Jackson is a famous purveyor of this lid.

Reggie looks great in his nacho helmet and dark glasses.

safety helmet

Offensive: synonym for "retard", "spastic", etc. Used in reference to safety helmets that some severely disabled people wear to mitigate head trauma. Can also be used as a derogative term for an autistic person that weaponizes their condition in order to cry-bully or coerce others.

The Earth isn't flat and vaccines are safe. Stop spewing bullshit, you fucking safety helmet.
