Something between radical and ridiculous. Spectacular.
That show last night was totally radidudical!
When a food item meant to be shared (such as brownies or pizza) is cut in an unusual and disorganized manner. The resulting pieces are of differing sizes and shapes. A result of trying to say 'cut all fucked up' but saying it wrong.
Those brownies at the meeting last night were delicious but they were all fuckcut.
