Meaning
A salt shaker, typically white or clear with small holes in the lid and grains visible inside. It stands for salt, seasoning and adding flavour to food.
Online it carries a strong slang meaning: being ‘salty’, that is bitter, annoyed or sore about losing. “Lost one game and he’s been 🧂 all evening” It also suits cooking chats and the phrase ‘take it with a grain of salt’ when something sounds doubtful.
