Someone who 'keeps it real' why they bop (walk) the streets. As the streets, indeed the world in general, becomes populated with more 'fakers' 'haters' and 'wannabes' the true bopper is a somewhat dying breed. Those who are remaining represent the real and refuse to go under the submerging forces of those with less integrity. One who maintains in the face of much hatred.
'He's always been a true bopper, look at the way he never gave up ever since we first saw him bopping these streets.'
