1. A large mass of land under the control of the great Khan/Mongolian empire.
2. A contemporary doom metal band consisting of former members of OLD, Burning Witch, Thorr's Hammer, and Blind Idiot God and current members of (among others) Sunn0))). Possibly one of the slowest, loudest, and creepiest doom metal bands ever, especially since much of the music is coupled with bass player James Plotkin's fantastic sequencing work.
Khanate is the loudest band I have ever seen; the entire room was vibrating through their set.
A Khanafer is usually an adjective used for someone who's insanely chill n' shit, but seems to attract a large amount of people. In other words, overrated. A Khanafer has no skill, no talent, no anything.
