I came across some puzzles with two words - titties & button - when I was reading "The Color Purple" by Alice Walker.
The original paragraph is
"Us sleep like sisters, me and Shug. Much as I still want to be with her, much as I love to look, my titties stay soft, my little button never rise. Now I know I’m dead. But she say, Naw, just being mad, grief, wanting to kill somebody will make you feel this way. Nothing to worry about. Titties gonna perk up, button gonna rise again."
So what do titties and button mean here? Something homosexual?
