In france we say "on a dit pas les mamans" which translates to "we said not the mothers" and the kid who said ur mom is in an unwinnable position to win the argument
So you agree that your "UR MOM" meme is pointless because the uno reverse meme exists so it's not effective to me.
You created a paradox saying that your meme is effective and not effective against me.
So when I type my opinion, you provocate me by saying ur mom. You didn't have to respond to me multiple times, I don't have to respond to you but I prefer that you lose time by responding to me.
