Ur Dogo homo

the most destructive insult in existence of the world. this insult hurts people in the place it hurts most, the heart.
this is worse than Ur mom gay, Ur dad lesbian, Ur granny tranny, Ur grandpap trap and Ur mom and dad gay together. you cannot use No u to deflect this.

Joe: Ur grandpap trap
Devan: Ur Dogo homo

ur mum

the mysterious figur who will come and beat you up if you shit in the sink at exactly 4:20am when you shout among us at the top of your lungs 69 times- she will also end up skimming your family.

What are you doing later?
Ur Mum.
