A cute, pink puff ball with a big appetite. He is Dreamland's greatest warrior and adventurer. Kirby's earliest adventures often ended with a battle against a giant blue penguin over a stash of Dreamland's food.
Is that Kirby? He is so cute!

A kirby is a sexy australian man who travels on planes trains and busses across America to meet his tinder matches. Activities of interest include pushing pale gingers against walls and kissing them, eating large quantities of roast beef sandwiches, and being cool as. Beware of kirbys, you will fall in love in 7 days or less.
Pale ginger: "Kirby just pushed me into the ocean after throwing mud at me, I think i love him"
Kirby "you're creepy so I love you too"

He's hot but a douche. The biggest jerk you will ever meet. he's the kind of guy to kiss a girl and get her hopes up then say he just wants to be friends. Also he thinks he's hilarious and a genius. He has the potential to be a good guy.

Girl 1: So what do you think of my new boyfriend?
Girl 2: I got to be honest he's a Kirby

2. Don't be a Kirby

Verb - To challenge an opponent to a more serious, higher-skilled game when losing a casual one; to strengthen rules in order to overtake a less-abled opponent. Not to be confused with TomCavanaughing, or "taking a casual game way too seriously."
"It was a great pickup game until Joe decided to kirby it up and started complaining about traveling and bumping."

A seriously fucking annoying teenage girl ages 12-16. Kirby's can usually be spotted in skin tight, ass-revealing yoga pants, and shirts that use the exact same amount of material as a bra. A Kirby's natural habitat is in the middle of a circle of horny guys in tank tops. Kirby's usually like to spend their days hugging every guy they see, uploading photos of them with obvious cleavage, and stealing the boyfriends of her best friends. Kirby's should be swiftly avoided by all of man-kind.
Kirby: OMG, Josh, come get tickets with me! LOL
