Rap, Dubstep, Kids who think they have "swag" because they listen to said genres of music, white kids who think they're black (no racism intended), stupid kids who are oblivious to anything and everything, people who can't spell, smoking, bronies (some of them).
Lastly, the thing that annoys me the most is people that say "K". Words do not describe how much that irritates me, the fact that 99.9% of people i've ever talked to on graal say that, it makes me want to stab myself with a rusty screwdriver.
