As in bring it on you look like Tarzan and fight like Jane Jabroni, come say it to my face so I can put my fist through yours, and then wipe my ass with it, bitch.

....or, someone saying to you "You and I have nothing in common" to which you respond to the Jabroni by saying "We both have something in common because we've both had sex with your wife".
