Possibly the most devastating words that could ever possibly be spoken by a human being, worse than ur mom gay, ur dad lesbian and even your granny tranny.
George: "Ur mom gay"

Peter: "Ur dad lesbian"

George: *On the brink of tears, using all of his might to conjure up the words* "Ur dog gay"

Peter: *Loses all fucking brain function and resorts back to a child like state, pisses himself and then fucking dies

After all the urs, this one is one of the most terrifying. “ur dog log” is to only be used if there’s no more hope.
joe: I didn’t think it’d come to this..
John: wait-no-joe
Joe: ur dog log
John: soul leaves existence and everything is abolished

The absolute fucking pinnacle of insults not only will they just be utterly demolished, this will cause the Mariana Trench to rupture and the Yellowstone Volcano to erupt. Then when all is said and done, the fucking moon will collide with the earth on the exact spot of the person who has been insulted.
Tim: Dude, fuck you.
Joe: Ur dog a frog.
Tim: What...?
Joe: *engulfed in flames*
*Yellowstone begins erupting as the world slowing falls into pieces from the Mariana Trench rupturing*
*The moon collides with the earth on the exact spot of Tim*
