its a meme! If you didnt know, this is a REAALLY popular meme on youtube. Its an animation were you are dressed up as your favorite animal, and you say "if a (your favorite animal) gets lonely, it will die!" and then its you pretending to be dead, then you throw your fake animal ears off, and you say "nyeh." all while that girl is watching you. Just so you know, that weird half circle thingey is your headband with fake animal ears. Plz draw the animal ears you are wearing in the animation on the headband. If you still confused, i am gonna make one with it all colored in. Oh, and look up "if a gerbel gets lonely" on youtube, cuz thats the original video.
