n. A very selfish, highly volatile, self-centered person. Also usually associated with common mood disorders, such as bipolar disorder, and often jealous. Occasionally, a caro may act classy, but usually simply acts as if the world revolves around him/her.
"Sorry, Jessica, I have to bail on our plans. I forgot it was my grandmother's birthday. I can't come over."
"Veronica!!! What the hell?! I don't care about your grandma and her stupid birthday! You promised you were coming over to watch movies and bake cookies today! You have to do it. I'm going to be miserable the whole day."
"Jessica, seriously, you're being a total caro. Stop. I'm sorry, but I can't."
"Oh my gosh, I'm sorry! I didn't mean to be a caro. I understand. Have fun!"
