flint

"flint" describes a piece of flint, such as a gunflint, used to produce a spark by striking it with a firestriker. Heard in rap lyrics, drill music, video-game chat or street-style social media, it is more often quoted than acted on. What matters is context: are they repeating a song line, or are they describing specific people, places and plans? If the language pairs with secrecy, sudden new friends, or worry about someone they know, that is the cue for a calm direct conversation, ideally before involving anyone else.

"flint" is informal English meaning a piece of flint, such as a gunflint, used to produce a spark by striking it with a firestriker. It is used widely across English varieties. A more formal or neutral equivalent would be something like "a piece of flint" expressed in standard vocabulary. A common mistake is to assume "flint" can replace its standard equivalent in every register; keep it for spoken or casual situations and use the formal form in writing. If you are a B2 or C1 learner, it is useful to recognise this word when you hear or read it, but think carefully about whether the situation really calls for it before using it yourself.
