This is another word for an African American. Right after slavery wasnt excepted in todays world, people started calling the blacks that worked for them "the help" so therefor they are "helpful". Donot get helpful mixed with any other kind of blacks, helpfuls will actually work and be nice about it... they know there place!
man, this is alot of cotton to pick, where is "the help" when you need it?
Sue- That black man was very nice by holding the door for me.
Me- Yes, He was very "helpful"
