anyone that is below you. It can be socially, economically, linguistically, intelligently, whatever, it doesn't matter. It is up to you to decide and is on a case by case basis. Though if you are calling some
rich bastard like
Warren Buffet a pleb than your first name should probably be Sultan, to put it in perspective. It is best to use the word to describe someone that is not around though because then they are not there to prove you wrong with a fat stack of cash or by breaking out
the queen's english or some crap. However, calling someone a pleb usually does not lead to a fight because they are likely too stupid to understand how much you have just insulted them. It is really best used to embrace your own current well-being, in good fun, with a underhanded insult on the dregs of society.
A guy walks out onto his pool deck in the middle of the afternoon with a tray full of double patron margaritas for his friends and lobster tails and steaks
on the grill and says "I wonder what the
plebs are doin today?" and then wonders if he turned on the security system at his
beach house.
