The phrase is Danish, with pissvaska used as a crude, joking insult aimed at Emil, and the XD in the original title signals it was shared as a laugh, not a serious attack. Its exact origin is unclear, so it circulates mainly as a short soundboard clip among Danish meme clips and gaming friends. Tags around it point to Danish slang and shut up humor, which helps explain its use as a roast reply. It stays popular for its specific name call, which feels personal even when reused on strangers.
