teflon idiots
People who think they are clever and believe their incoherent rambling is insightful and factual but to the contrary is lacking in depth or information. These people believe they have always won a debate because they are the last one left in the conversation once everyone else has left out of exasperation filling them with a sense of victory.
I spent 45 minutes explaining to Beth why the dress is actually black and blue but she still believes it's white and gold, she's just one of those teflon idiots.
