A common saying and good advice for men thinking about having sex with a crazy bitch.

Usually a woman that:

Never shuts the hell up, has an annoying high pitched voice and laugh, gets way too overly attached, has shaved/short hair, stares into your sole, has bigger muscles than you, believes there's more than two genders and calls herself a feminist.
"Dude I fucked this crazy chick last night and woke up and found my dick in a jar."
"Never put dick in crazy bro"
Get the Never put dick in crazy mug.
