Crouton-Brain
A crouton-brain is a term used for individuals who are overall a waste of space. They more than likely are uneducated, but feel the need to be heard, ill-mannered and have a sense of undeserving self-confidence... although some are disguised as attractive on the outside. Typically a crouton will pretend to have similar interests to fit into the social setting they placed themselves into, and do not carry a sense of individuality, sophistication or class. Lacking any true intellectual substance or awareness.
This crouton-brain I saw at the bar wouldn’t stop talking about politics while drunk and it was obvious by their vocabulary they were uninformed, but continued to scream at strangers and spill their drink.
