Dennis 

The invisible duck that follows people around spontaneously making quacks that miraculously sound like farts.

.....fart.... "Hey did you hear Dennis? Where is that little bugger?"

Dennis 

A person that is extremely smart and imaginative. He is nice overall, at least that's what people think. He actually has no feelings at all! Scientists have a theory that a Dennis is cold blooded

Dennis might be cold blooded...I'm scared

Dennis 

If someone is swearing alot in a conversation they should be temporarily named Dennis. The words fuck, fucking or fucked are the most commonly used by Dennises.

Person 1, I've just fucking broke down in my fucking car for fuck sake it's completely fucked.

Person 2, alright Dennis

dennis 

Hillbilly, white bread, chicken humpin cracker, suffering from 10 days of funky sack, hygiene is for shit, doesn't bathe and wears the same clothes for a week. Smells like a moldy jack rag. He's also fighting a loosing battle against beard dandruff, which during breakfast, can leave "snow" in my sweet sweet syrup. Chain smoking to the point that he reeks of fumunda cheese and ashes. A work out consists of eating a fun size bag of m&m's, and after only 2 he's in need of mouth to mouth, but is only worthy of ass to mouth.

That nasty mother fucka, needs to go home and engage in some pit and taint scrubbery, change them funky drawers, and pop a tic tac, just being near him makes my eyes water and burns my nose hair, smelling like a week of rotten back ass, what a dennis.

Dennis 

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.
