the combination of being both sour and
bitter
In
chemistry, acids are usually described as being sour, whereas bases are described as being bitter; the neutralization of an acid and a base produces a
salt, and thus, salty.
The folks: That old man Jenkins was so
bitter about our parking in
front of his mail box. I've never
seen a more sour expression...
You: Oh wait, so he was like salty?
The folks: ohhh...hon, is that how you talk during job interviews?
