aesthetically challenged

Distinctly unattractive or unpleasant to the eye; ugly. (Pseudo-politically correct slang used for humorous effect.) Deborah's new boyfriend is a bit aesthetically challenged, but she loves him and I guess that's all that counts. A: "Her dress was, ah, a bit aesthetically challenged." B: "That's putting it nicely—the pattern and colors were hideous!" Phil's somewhat aesthetically challenged, but he's a really sweet and intelligent guy.
