Fabboon
A person who's so confused they think the sky is green and the moon is made of mashed potatoes. They're like a baffoon but with more swearing and less sense.
'I thought the president was a robot. Now I think he's a fabboon.'
'Why is my dog wearing a hat? Is this a dream? I'm a fabboon.'
'I lost my phone, my keys, and my mind. I'm a full-time fabboon now.'
