The phrase comes from Indonesian online slang popular in gaming and social media communities, where players jokingly call skilled friends puh sepuh while calling themselves pemula. Ajarin dong, meaning teach me please, became a shorthand for that humble dynamic and spread through short videos, streams and memes that paired the line with clumsy gameplay. It remains popular because the contrast is instantly recognisable to Indonesian audiences, even without context, and it works as a quick setup for failure, learning and friendly teasing.
