«عَامِلْ أَمِيرْ فِي جِلْدِ خَنْزِيرْ»

The saying mocks a person who parades as someone noble and important while remaining, underneath, coarse and contemptible. The lofty title is only a role being acted out (the opening word means 'making oneself out to be', not 'worker' or 'governor'), and the animal hide wrapped around it shows what the person truly is.

Its broader point is that pretension cannot hide a base nature. Borrowed dignity, haughty manners, or a show of rank do not change someone's real character, and observers can still see the crude creature beneath the costume.

Aim it at someone whose grand manner clashes with their actual conduct or character, such as a boor playing the dignitary or a petty person demanding deference. The pig image makes it a sharp insult, suited to biting criticism rather than gentle teasing; expect it to offend.
