Come and smell!
"Come and smell!" is used typically in fights between two alpha males. If one of the males requests a dirty offer, such as "Suck my dick!" or "Eat my ass!" then the other male's best choice is to use the phrase "Come and smell!"

This means, that the male who has used the dirty insult against the other male, will need to do as offered and smell the other's pee pee or whatever
