look up any word, like sex:
 
1.
Beautiful, especially to the sight, but also the mind and soul.

2.
Ugly, but in a unique, appealing, and/or interesting way. A combination of the words "beautiful" and "hideous"
You're beauteous. Your nose is wrong, and I sing this song, 'cause there's too much focus on body image.
