Mild expletive of frustration, exasperation or amazed disbelief, derived from a softened Hokkien profanity (originally "wah lao eh", a euphemism for a stronger phrase referencing one's father). Sits somewhere between "oh my god" and "for crying out loud" in English — strong enough to convey real feeling but not actually rude. Common variants include "walao", "wah-lau" and "wah lao eh". Examples: "Wah lao, again ah?" "Wah lao, so jam today." Used by all ages and registers in Singapore and Malaysia.
