Itâs an old Persian saying for when someone is trying to point out that there is nothing but shame in being an ass-kisser to an ass-kisser.
A: Hijab is a culture for all our Iranian women and we should make sure everyone wears it at all times.
B: Shut up man, the dog fucked the ass-kisser.
In this example, person A was trying to support the forced hijab rule and cover it up by calling it culture.
