I've never really identified with the term low-key. 

Technically, low-key means keeping something chill, or more restrained, but most of the time that doesn't really work for me. I'm more obsessively high-key. When I like something, it's not just "cool" or "great," it's "THE BEST THING EVER," or "OMG AMAZING." I tend to be really into the things I love, whether it's a place (hey Nashville!), a person or pet (don't get me started talking about my kitten Holland), or a movie (I had a regrettable Lord of the Rings phase early in my high school career). Conversely, the things I don't like tend to be "THE WORST THING EVER," (don't get me started on the word nestle). 

Perhaps unsurprisingly, this also applies to most of my wine drinking experiences.
