Alexander Anderson is the Irish vampire hunter from Kouta Hirano's Hellsing manga and its Hellsing Ultimate anime adaptation. This exaggerated roll call of Irish surnames comes from the fan-made abridged parody of the series, where his cheerful priest persona is pushed to comic extremes. The line became a shareable reaction clip on YouTube and meme soundboards, passed around by anime fans who recognized the joke instantly. It endures because the escalating list of names works as a plug-and-play greeting for introductions, parody dubs and convention edits.
