Meaning: Salty means ‘tastes like salt’. Recently, young people also use it as slang. The slang ‘salty’ means ‘in a bad mood; usually because he/she didn’t get what he/she wants’. It has a nuance of ‘childish’ too. Taste words often describe people’s attitudes. ‘Sweet’ means ‘kind’, but most other taste-words are negative: ‘sour’ (miserable), ‘bitter’ (holding onto an angry feeling) and ‘salty’ (in a childish bad mood).

When is the last time that you got salty?
