What Does "Sourpussed" Mean?

"Sourpussed" is a slang term that is not widely used or recognized. It is possible that it may be a regional or informal usage, but I couldn't find any definitive information about its meaning or origin.

However, based on the context of your question, I can make an educated guess that "sourpussed" might be a playful or colloquial way of describing someone who is feeling grumpy or dissatisfied. The word "sour" suggests a negative or unpleasant quality, and "puss" could be a slang term for a person, especially one who is perceived as being overly sensitive or demanding.

So, if someone is "sourpussed," they might be acting in a grumpy or irritable way, possibly due to some perceived slight or disappointment. But again, this is just a guess, and I couldn't find any definitive information about the meaning of this term.
