a person who is an idiot and shows it all too well

I couldn’t care less (but one must keep up appearances, right?)

1 - Someone who treats people unfairly for little or no reason.

2 - Person with a penis on their head.

A group of people who profiteer during a pandemic and buy up all the supplies of hand sanitiser and food, then proceed to sell it at extortionate prices on various online sales outlets. A petition has been set up to name and shame these DICKHEADS!

when someone is acting like a really big dick

One who behaves in a particularly obnoxious or selfish manner; as though they have cum for brains. A jerk.

Any person who is always right, and when questioned will come back with something witty that will make you sound so stupid, you will never want to challange again. Personal subjects will be thrown out there, and tears usually follow. Will constantly point out your negatives and will just generally make you feel worse about yourself. This person is usually very good at comebacks and will not take offense to anything.
