The phrase Allahu Akbar is a traditional Arabic expression meaning God is greatest, used in prayer and everyday religious life. Online, this particular recording became a short meme clip because of the unexpected hey added after the shout. It spread through soundboards and short video edits, where users paired it with explosion jokes, sudden fails and over the top reactions. Its continued use comes less from any single source video and more from how instantly recognisable the delivery and timing are.
