Learn English – What does NOOT mean

To provide a smidge more detail, the movie Groundhog Day is about a man reliving the same day over and over and over. Every time he wakes up it's Groundhog Day again, and people always say the same things and do the same things over and over, and he's the only one who is aware of the infinite repetition and who is capable of doing things differently.

The "Partridge Dictionary of Slang" has an entry for "Guinea people" as a synonym for "Jamaicans with strong sense of African identity".

In addition, p214 of the Jamaican English Dictionary, you will find this entry:

GUINEA-MAN sb; cf OED 2 1830 → A man born in Africa.
a. 1818 Lewis (1845), "On hearing of this fresh instance of devilism, I asked her mother 'how she came to have so bad a daughter, when all her sons were so mild and good?' 'Oh massa', answered she 'the girl's father was a guinea-man'.

Other entries (like Guinea ship for instance 'a ship bringing slaves from Guinea (Africa)') suggest that the Jamaican meaning of Guinea is Africa and that a Guinea man is a slave born in Africa (as opposed to one born in a colony from slave parents).

Considering that this cannot be a valid meaning nowadays, I'd surmise that this is the name that non Jamaicans would use to designate Black Americans of Jamaicans origin as stated by the Partridge Dictionary of Slang.
