Wa Alaikum Assalam is the traditional reply to the Islamic greeting Assalamu Alaikum, which means peace be upon you, and the reply adds and upon you be peace. The spelling Valekum Aslam is a phonetic version typed by users searching for how the phrase sounds. Short audio clips of the greeting spread through messaging apps, soundboards and short videos, where it became a light hearted way to welcome someone, answer a hello or mark an entrance without needing a long explanation.
