Singaporean slang (Singlish) for someone who's slow, dense, or out of the loop — basically calling someone a block of wood. 'Kayu' is the Malay word for wood, and the implication is clear: you're stiff, thick, and not processing things at normal speed. It's used affectionately between friends or as a mild insult depending on tone. Classic Singlish energy: borrowed from Malay, delivered with a smirk.
Why so kayu lah, I already explained three times how to use the group chat.
