Probably one of the most hurtful insults that can cross your tongue. Used only in extreme circumstances to completely obliterate the other person.

The greatest insult of all time. Saying these words can actually destroy the very fabric of existence itself, if used in a roast battle properly. Luckily, this will likely not happen, as anyone who uses them in a roast battle can’t even finish the words before being decintegrated as they couldn’t comprehend the sheer power of this insult. The other person being roasted though is decintegrated too. In fact, everyone within 69 kilometers of this saying is decintegrated. As you can tell, it is the spawn of “Ur mum” and “Ur gai”. It has many siblings, such as “Ur dad lesbian”, but none come close to the sheer unfathomable power of these words.
