Tvoyu mat is a long established Russian swear expression, literally referencing your mother but used much like a strong English expletive when someone is angry or exasperated. Short shouts of the phrase circulate widely on Russian speaking social media, gaming chats and meme soundboards because the wording is instantly recognisable even in a one second clip. Non Russian speakers also reuse it as a generic angry foreign outburst in edits. Its brevity and familiar place in everyday swearing keep it popular as a reaction sound rather than a longer quote.
