I need some help with naming my oc. Does anypony have any good suggestions?

She's twilight's second cousin and they have everything in common except that my oc loves pranking. Both of them are Princess Celestia's students. My oc's flaws are that she tends to worry a lot and be pretty lazy and annoying. Most people get creeped out by her but she can be an extremely good friend when you get to know her.
