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!

Get the yo-yo mug.
A term used to address a person of comically high idiocy and an even higher lack of sense. More scatterbrained than a clown, yet more class than a shmuck.
They forgot their credit card in the restaurant card sleeve? What a yo-yo.

Get the Yo mug.
As used in the 2007 ossim film Juno, to answer the phone.

A quirkier way of saying hey.

Only to be used with close friends/family members, as can cause confusion (Unless previous conversation about this greeting has occured/watched Juno with the person and have discussed that line)
USED CORRECTLY-
*ring ring...ring ring...ring ring*
A- *looks at phone, recognises caller*
A- Yo yo yiggity yo
B- Whats the haps home skillet
*coversation continues in supercool urban dictionary esque lingo*

USED INCORRECTLY-
*ring ring...ring ring...ring ring*
A- *looks at phone, recognises caller*

B- What?
A- Oh, sorry I just meant hey... I thought you got that yo yo yiggity yo thing?
B- No. I did not.
*embarrasing pause*
A- Sooooooooo
