Someone started it as a joke (on 8chan or some other dumb board?) that it made the 'WP' symbol for white power and were running around being edge lords. Then actual white supremacists started using it as an actual WP symbol. I think that's mostly in the US and in a certain age group, but one of those stupid meme trends.
Similarly, not even sure what it was called, but there was something stupid going around about twenty years ago with guys making that symbol upside down around waist level, and if you saw it, you were 'caught' and got a nut shot for it. So dumb, but was funny when I was in my early 20s I guess. So was a lot of other stupid things that would probably get me canceled today, so glad I grew up doing stupid things before cell phone cameras and social media enshrines it forever on the interwebs.
And sometimes it's just the okay symbol, so I guess context is everything. Sometimes it's just easiest to not ovethink things.
