Salty describes something that contains or tastes like salt, the mineral that makes ocean water undrinkable and makes popcorn delicious. When you accidentally get seawater in your mouth at the beach, that sharp, slightly harsh flavor is saltiness. Potato chips, pretzels, and French fries all taste salty because they're seasoned with salt.

The word also describes someone who feels annoyed, bitter, or resentful, especially after losing or being embarrassed. When a friend beats you at basketball and you snap back with a mean comment, they might say you're being salty about losing. Someone who's salty about not getting picked for the team might sulk and complain instead of accepting the decision with grace.

The difference between feeling naturally disappointed and being salty is how you handle it. Disappointment is normal, but saltiness adds an extra layer of bitterness or hostility that others can sense.
