What does Kenya hate Denasia?

Kenya hates Denasia because she believes that Denasia was gossiping about her.

“Ooh! I can’t stand her,” Kenya seethes. “The other day, we were in line in the cafeteria, right? And she behind me, talking out the side of her neck. She didn’t use my name, but I know she was talking ’bout me, saying I tried to get with DeVante.”
