A term the Ying Yang Twins use in most of their songs, they even made a song called Hanh! on Me & My Brother. In the context it's used in the song 'Hanh!', it's used to mean 'no other' or 'a mother (see example 1)' also, in the chorus, it's used to mean 'wtf?!' I think, as far as I can tell, either that or it means 'nag' (see example 2)
1 "Nigga's stay crunk like HANH!" -Ying Yang Twins, Hanh!
2 "Think we ain't crunk, they think we playin, all around the world that's what they sayin' Hanh! (several different times)"
