Most commonly, thick is a term used to describe someone who’s not skinny, but not fat either. They usually have large boobs or a large
ass, and are proportionated
like an hourglass. It is also spelled “thicc” at times.
Thick can also be used as a synonym for stupid, and is usually used as a
slang term in the UK and other surrounding areas.
“Damn, did you see how thick that
girl is? I want a piece of that
ass!”
“Are you thick? Why would you
think such a stupid thing?”
