A type of wrong grammar, as it could not be used in a single question: What that mean? This phrase could be used at the end of a question sentence, but there must be an 's' following the 'mean': Do you know what that means? This is already accepted in the English Language, as the phrase is often used in the public.
A: Fk you!
B: What that mean?
C: (Raise his middle finger)
B: What that mean once again?
A: To have sex that mean.
