Used to describe feces.
I have to get home quickly. I have to take a huge uckie.

I've had really bad uckie farts all day long.

An Uckie is a Yuckie.

This word is used interchangably (and equally effectively) as both a noun and an adjective. An "uck" or "ucky" is someone who is portraying more than the usual amount of maliciousness, selfishness, butt-headedness, or just down right stupidity. A person can be described as "ucky," but does not quite qualify for the "uck" status. "Ucky-bucky" is the epitome of uckiness.
noun: "Rachel has been such an uck lately...Katie also thinks she is a real ucky-bucky."

adjective: "I can't believe Rachel ate all the speghetti...that was so ucky of her!!"
