Like one that would automatically make them teary eyed and just induce emotional damage at a deep level very quickly.
Like if you are in the middle of an argument shouting bullshyt after bullshyt at each other, what is one vicious distinctive line that make them shut the fuk up on the spot?
Would be great if its an insult that can be universally used.
Like for example everyone knows if you see a fat ass walrus looking women and you said "your fat as fuk cuz" they would break down but you can't really use it on someone who's in shape.
I want to know this info just for future precaution.
