Get the ur mom libmamug. This statement is single handedly the worst statement known to man nothing can counter this statement not even the statement "no" u which is also a very terrible statement. The statement "ur mom gay" has been linked to many terrible disasters like cherynobal and the september 11th attacks and theres some speculation that links these uttering words to the creation of ISIS. People say that this terrible statement was invented by NATO to help with the Americans in the vietnam war sources say that these words on the loud speaker would make the charlies run out of the woods with there penises bleeding.
