Kau tipu aku is Malay and Indonesian for you lied to me, and the phrase circulates online as a short reaction audio for calling out deception. It is popular in Malaysian and Indonesian meme communities on TikTok and WhatsApp, where users send it as a voice-style jab after a prank or a broken promise. Because the meaning is instantly clear to Malay speakers and the tone reads as playful outrage, it keeps getting reused in skits, gaming clips and everyday joke videos about being tricked.
