UCB's = abbreviation for Uncooked Chocolate Bars.

The most amazing of amazing chocolateybiscuitness made by Tubs using her own secret recipe. (by secret we mean one that you could probably get anywhere but she has the magic touch)
"oh my god Tubs those UCB's you made are yummy"

A show in the late 90’s early 2000 on Comedy Central. Stood for Upright Citizens Brigade. Sketch comedy at its finest.
Can’t believe Comedy Central took UCB off the air. Little Donnie was awesome
