Fro-yo girl here. You have to watch closely to see it (don’t blink) but fro-yo is mentioned and shown (looks like a vanilla/chocolate swirl with Fruity Pebbles) in the Discover Card 5% cashback commercial. It flashes by so quickly that I often only hear fro-yo and don’t see the fro-yo. But you can watch it as many times as you like on YouTube.
You know you love me. X0 X0, fro-yo girl.
