A samart style side teep. I personally feel like I don't see it that much, at least out of fights I've watched and the ones I've taken part in here in canada across a few different styles. Most people I've seen throw it in my experience either only turn their foot and hips slightly, like less than 45 degrees, or do a karate style side kick with a full chamber and hip rotation.
Curious what you mean about it leaving you pretty exposed, I don't see it. At least, no more than a round kick that misses.
