Haram Alarm is a meme where if someone commits a sin, or anything at all really, someone says "What's that sound? It must be a Haram Alarm." Many other phrases can be used but this is the main one.
Guy 1: "I love bacon." Guy 2 : "Do you hear that sound?" Guy 1 "What sound?" Guy 2 *turns head 90 degrees* "It must be a ... Haram Alarm"
