a yo-yo is a phenomenom where you can say what ever you want to a girl, and within less than 5 minutes, that girl will come running back to you,like a yo-yo, with your chances of action increased exponentially. This is accompanied by making the motion of using a yo-yo, and saying 'yo-yo' under your breath
Me: you slut bag whore, you cunt scab licking AIDS infected bitch, you dirty pirate hooking bitch, you bull dike cock sucking hoe bag!
(girl runs away in tears)
(girl walks back in seductively)
Girl:heyyy, you wanna go upstairs?
Me:yo-yooo!
