hai ngoc la
A guy with a cock that's just okay. Not bad, but not great either. It's like a B+ in penis grades.
My uncle's cock is Hai Ngoc La. It’s not bad, but it’s not worth the trouble of staring at it for hours.
My brother told me his friend’s cock is Hai Ngoc La, it’s just average, but he still bragged about it.
My neighbor's cock is called Hai Ngoc La. It's like a middle-of-the-road sandwich.
