When a man complains a lot, one says he has a vagina. When he complains even more it means he has sand in his vagina. But when a man continues to complain, he slowly turns that grain of sand into a pearl. Therefore becoming a "pearl farmer".
Nick: "Man, this sucks, I just moved that yesterday, now they want me to move it again today. My fucking back is killing me"
Jerry: "Dude, quit being such a pearl farmer and just fuckin' move it."
