Brain-Weasels

Intrusive thoughts of self-doubt and despair, often associated with depression or anxiety, that crawl into your brain and make it hard to focus on other things.

I was going to go to the party, but my brain-weasels were so bad that I couldn't deal with other people that evening.

Brain-Weasels

A common condition where someone makes repeated grammatical errors, often followed by hysterical laughing and joking. The only cure for brain-weasels is to suffocate them by smothering the victim with a pillow.

Crap, you're infested with the BRAIN-WEASELS! Quick, smother him/her with a pillow.
