Regional and speaker variation
Local language is never distributed evenly. Age, neighbourhood, family background, profession, friendship group, online communities, and the formality of the moment all affect whether this expression sounds current, familiar, marked, playful, or unusual. A term may be widely recognised without being used every day by everyone from the place. Treat the regional label as useful context, not as a claim that all local speakers share one vocabulary or accent.
How to interpret the examples
The conversation above demonstrates one realistic function, not a script to copy mechanically. Notice the relationship between the speakers, the situation, and the reply. Before using the expression yourself, compare several complete exchanges and listen for tone, pacing, and what follows. When uncertainty remains, plain respectful language is usually more natural than forcing a local term solely to sound authentic.
