Not so easy on the eyes

A lot of phrases in English are understatements, as if we don’t want to commit too much to what we’re saying.  One of them that springs to mind is easy on the eyes, which is another way to say someone is good looking, sexy, beautiful.

In Chinese, there is the opposite.  The word they use for ‘ugly’ is 难看 (nánkàn), which is, literally, hard to look at. Ouch. The Japanese also have the word バックシャン (bakku-shan) for someone who appears hot from behind, but not from the front.

Do you know any other interesting phrases for someone who’s not so easy on the eyes?

*Note: looking up ‘ugly’ on Google Images isn’t really that good of an idea.
