That dancing anime girl is from this video, "loli god requiem" https://www.youtube.com/watch?v=Ci_zad39Uhw

It's a video of an underage-looking ("loli") anime girl insulting the viewer for being a pedophile.

At this point it's mostly used by pedophiles in a sorta tongue-in-cheek way.

Of course, all the best security professionals are either pedos, israelis, furries, or all of the above, so it's not really surprising.
