Adam "Pacman" Jones is telling his side of his recent arrest ... sharing a clip to Instagram he says was taken just before police arrived -- where it appears people inside the hotel called him the n-word.
The former NFL cornerback released a video Sunday morning ... showing what he says is the prelude to his eventual arrest -- starting when a woman clearly yells out the racial slur as Jones and his party are walking out the front of the Loews Arlington Hotel. It's unclear if she was yelling the word at Pacman.
