f(c)=f(d) <=> ac+b = ad+b <=> c=d

Injected the Bleach

An updated version of "Drank the Kool-Aid" specific to supporters of Donald J. Trump who so blindly follow them that they even defend and try to explain away his suggestion during a nationally televised news conference that "bringing light inside the body" and "injecting disinfectants" could be a possible cure for Covid-19.

"My crazy Aunt is such a Trump supporter, that she is trying to say Trump was really referring to cutting edge treatments not publicly known about yet. Even though Trump now says h is comments were sarcastic."
"Wow, she has really injected the bleach."

stink injection

When a person or animal passes gas when one's buttocks is in direct contact with the furniture where one is sitting so as to make the smell of the flatulence stay in the furniture after one leaves the scene. As a practical joke, this is sometimes followed by someone else sitting in the same spot moments later, only to push the foul smelling flatulence back out into the air where one can breathe.

Person #1: Why is James flailing his hands in front of his face?

Person #2: Because I just gave that couch a stink injection.

(high fives)

Person #1: Good one Bro!
