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."
