https://en.wikipedia.org/wiki/Reappropriation
A reclaimed or reappropriated word is a word that was at one time pejorative but has been brought back into acceptable usage, usually starting within its original target, i.e. the communities that were pejoratively described by that word, and later spreading to the general populace as well.[2][1][3] Some of the terms being reclaimed have originated as non-pejorative terms that over time became pejorative. Reclaiming them can be seen as restoring their original intent. This, however, does not apply to all such words as some were used in a derogatory fashion from the very beginning.[1]
