The act of being obsessed with Miley Cyrus, so much so that people think you are a lesbian. However, since you are not attracted to any other girl besides Miley, you are a milesbian. This word also applies to people who love Miley for the sole purpose of staring at her legs, and are completely turned off by her music and personality.
Holy shit, did you see Miley at the MMVA's this year... her legs were so hot they got me becoming a milesbian.
