expr. (Used as an expression) can be used by people to express frustration, anger and impatience.
Phrase can be traced with a south-east Asian origin, mostly used in Singapore and Malaysia. Wa (我)Lao (老)

literally means 'my father' in Hokkien (福建话), one of the most common dialects in Singapore and Malaysian Chinese descent. (hence it is used to scold blame the entire situation)

"My dad is responsible for this!" - for Anglo people equivalent

Inf. (Informal) This phrase is used for gangsters in coffee shops around "unschooled middle-aged to old people" hanging around roadside hawkers, food courts and coffee shops. Laypeople and commoners just go Wa Lao Eh as a small mantra in their hearts when something goes wrong.
(In singlish) "Aunty, got Kopi-O or not?" Aunty (coffee shop owner) :"No more liao"

"WA LAO EH"

(For Anglo-looking people who doesn't get what the hell is this) It meant:
"Hi, do you have coffee here?" The owner replies: "Sorry, we've ran out"
