Ya majnoon Abu Abeer circulates online as an Arabic reaction clip shared through soundboards, short videos and messaging apps. The phrase itself is a colloquial way of calling someone crazy, and the Abu Abeer name gives it a specific, personal feel that makes the line stick in memory. Its spread has come less from a single known source and more from repeated reuse in edits, where creators keep the audio intact and let the timing do the work. That reuse has turned it into a familiar shorthand for disbelief at someone's antics.
