You shouldn't call your friends names.
Alex has a group of friends over to swim in her pool, one of which, Jaime, is insecure and uncomfortable about wearing a swimsuit.
Alex wants to compliment Jaime on her swimsuit.
Alex tells Jaime her swimsuit looks gorgeous on her and asks where it's from.
"Alex tells Jaime that her swimsuit ""looks good for being on a fatty""."
Jaime feels more confident after being complimented and is able to enjoy herself in the pool.
Jaime runs out of the pool crying and never speaks to Alex again.
