Something else....squirrels.
What's more annoying: Frozen, Minions, Minecraft, Emo Bands, or something else?
Spammers and people who act like they're so wonderful online all the time but they really aren't when you speak with them much.
Let's see:
Mosquitoes, political parties, and shallow people.
Racism, sexism and all sort of small narrow minded people.
People who interrupt you before you finish your sentence. Although that Frozen song is pretty annoying.
People without common sense.
