What does uckers mean?
Uckers is a slang term for a woman who is particularly gifted at, or frequently performs, fellatio.
Where does uckers come from?

Uckers broke into popular media in the 2015 song “4 Door Coming” by British rappers, 410. 410 is a British gang based out of Brixton, London and central to a genre of music known as UK Drill. In the song, one person raps: “Tell a bitch keep her face down / Who ever told you we’re lovers? / Three balls on her tongue / Uckers, badders.”
Uck is Multicultural London English slang for oral sex (likely from suckǰڳܳ or an imitation of the sound) and badders is London slang for a person who is sexually experienced. Uckers badders, then, is a woman practiced at the BJ.
“4 Door Coming” helped popularize the term among hip-hop fans and youth more generally. After its release, uckers and uckers badders caught on as slang for a fellatio or a woman who performs it on a man.
