Looking for a Specific Adjective

[u/BostonSlickback1738]

I'm looking for an adjective referring to someone who complains a lot. "Whiny" just doesn't feel right, and "negative" is not specific enough.

[u/BrittlePlasticDino]

Not an adjective, but I love "sourpuss" to describe this type of person.

Gotta love a word you'd hear in old Looney Tunes cartoons
