When somone is depressed and life isn't going so well for them.
"I been in a ugly mood lately"
Oh man what's been going on?
"I been in a ugly mood lately" Is a way of saying you're depressed and there isn't any way to fix it, or that you have been feeling depressed for a long time now. It can also be a way kf saying you're depresses but not making it seem like it's a big deal.
Hey man you look down, wanna talk about it? Nah its just "I been in a ugly mood lately"
