A word that people who are too much of a pussy to call an awesome an awesome to use to describe an awesome (even though asshole is simpler language).
The guy had known he was an asshole for a lifetime already, but the girl wanted to try and either go over his head or around the bush about what she really wanted to say to him, that way he could always stay either the rude one or the polite one,and she could keep a little control over someone else, since it made her feel like she had control of herself (which felt powerful rather than weak), so she called him unique.
When you've traveled to almost everywhere in your state and can't find a sternwheeler to ride on, and you realize you have to take a trip to the mississippi river to get on one, you know how a sternwheeler can be a unique thing to have. But you don't know until its gone usually.
It's a good thing you like to travel, since all the unique things to do are out of state or overseas now.
