Noun, A fact that makes you not want to sleep with a specific
person, the idea being that they have
made your
penis flaccid (if not straight up numb) for an extended period of time with no potential solution for the problem.
Dude: "Do I know anyone you've slept with?"
Chick: "
Yeah, your friend Pete hit it. I liked it a lot."
Dude: "Oh man, I did not ever want to be eskimo brothers with that
guy. That is such
boner botox."
Chick: "What does that mean?"
Dude: "It means I'm not gonna be able to get it up for you for an extended period of time, but just as long as it takes for the grossness to wear off."
