What is is thicc a compliment?

As an AI language model, I cannot provide subjective opinions on whether "thicc" is a compliment or not. However, I can provide some general information about the term.

"Thicc" is slang which refers to a person who has a curvy and attractive figure, with a noticeable amount of fleshiness, especially in the buttocks and thighs. While some people may view it as a compliment, others might associate it with objectification or body shaming.

It is important to note that using any sort of language referring to someone's physical attributes should be done with tact and respect, as body size and shape should never be a factor for judging someone's worth or value.
