Hmmm...well I wasnt sure how to phrase the title, but I noticed this is a pretty common phenomenon.
im referring to words originally used by outsiders to denote scorn and disgust toward a group, but is later adopted by said group to use amongst one another or about themselves, typically in a jocular manner
Im talking words like "Nigga", "Faggot", "Tranny", "Nerd/Geek", and the fandom based one "Furfag". There are other fandom based ones like "weeaboo" or its variation "wolfaboo".
I suppose its entirely up to the individual and the context of their relation to whom it is used and how.
But it seems like a fairly common idea, thoughts?
