The act of complaining and bitching, frequently consists in a high-pitched and earsplitting sound. Whining is a total kill-joy.
No one wants to have a whiner at a party.

This is what people frequently accuse each other of on the internet to make themselves look dominant, manly, or grown up, due to the fact that they don't actually feel this way in real life. The tactic frequently backfires, however, when the accuser displays his lack of basic grammar skills or lack of knowledge of the caps lock key.

Thinking of a minimum wage job as sub-serviant work, or of the people you work for/with as slave drivers is called whining. At a minimum wage job you don't get paid much but you do get paid something. Nobody likes a minimum wage job, but whiners haven't had to be anything closer to sub-serviant than anybody else who worked a minimum wage job.
At least you get paid, people who didn't get paid for doing work as kids aren't whining about it.
