Origin: In the T9 texting system, if one tries to write "okey dokey," the first words that show up are "oldy foldy."
(Rachel and Noah are texting each other).
Rachel: I'm gonna wear my cool hat tomorrow okay?
Noah: Oldy foldy.
simply put, a weirdo. Orginally found when texting using T9 mode and someone tried to write "Okey Dokey"
Katelyn: "OMG these rainbow cookies are a circus full of fun!!!!"
Stephanie: "Calm down Katelyn... quit being such an oldy foldy."
