Tom Hanks' Son Chet Haze -- Lets N-Word Fly, Uncensored ... But He Has Limits

Chet Haze wanted to say it ... felt he had the RIGHT to say it, so he did it -- he unapologetically dropped the n-word on camera.

Tom Hanks' rapping son posted the vid, attempting to clarify his earlier statement -- that he identifies with hip hop culture, so that makes it alright for him to use the word.

Don't worry ... Chet says he'd never walk up to a random person and say, "my n**ga."
