Irish slang for a kiss and a hug, usually kissing the cheek while holding the person receiving the fondie.
Primarily said towards children and not adults.
Mam: "Alright, folks, we're heading off! Give yer nana a fondie before you leave."
Oh my god, Tiffany, check out that foddie! If he was a few years older, I'd totally date him. He's gonna have all of the chicks on his back later in his life.
