My high school class was in mid-'00s, and there was one girl who very much had that butch/tomboy vibe going on. I drifted away from the class, so only heard rumours after graduation, but I think she never actually came out as anything. On the other hand three others of us (two of whom, including myself, I never would have guessed back in high school) eventually came out as various shades of queer :D
