How it's used

Deriving from the Cantonese slang for being 'at the bottom of the list' or 'last place', this term is a harsh way to label someone as incompetent or hopeless. It functions as an adjective to describe a person's lack of ability or a task performed poorly. Because it carries a strong derogatory tone, it is best avoided in professional or polite settings.

Examples

He is really useless at work, always messing everything up.
Are you incompetent? You don't even know how to do such simple things.

very incompetent

Common mistake

Do not confuse this with the literal ordinal number ninth, which is also written as 第九. In casual speech, the context usually makes it clear whether you are referring to a sequence or insulting someone's intelligence.
