The best creeper you will ever have, if you're lucky enough. Dennis is the perfect excuse for getting those ghetto/redneck/weirdo creepers off of you. He is a chill person, easy to talk to, and has an addictive personality. He has great luck and hosts the best Dr. Pepper parties. He's someone you're going to want to stick with because of the way he is. You may see him around for years and then when you finally get to know him you'll wonder why you let yourself miss out on this for so long.

Warning: texting him he will keep you up past your bedtime because it's just that enjoyable.
Also, do not be mean to him or else he will send an evil geometry teacher after you.
Dennis is awesome.

Sorry boys, I only have room in my life for one creeper, and that's Dennis.
