Gibbies are like hypies. You know.. when you are really, really hyper or excited? I guess the single form of "gibbies" is "gibby." If you got a high score on a video game or something.. and you were kind of expecting it, and you - with out emotion - are like, "YES." ....thats a gibby. But if you HAVE the gibbies usually you have more than one. :) I'VE GOT THE GIBBIES RIGHT NOW!

(n.)

1.

A nickname given to any pudgy kid that resembles the characters Gibby from Teen Nick's iCarly. Most often, this pudgy kid is known especially for trying too hard to fit in, acting as wankster as physically possible, and hitting on underclassmen and upperclassmen alike.

-Can be substituted with Gibbs, Gibblets, Gibble, Gibbly, Gib, or Gibbamundah-

2.

Someone who is terribly awkward when it comes to girls. Tries to force the annoying one-arm hug on them.
1 "Wow, Gibby sure tries too hard. If he just toned it down, he'd probably get some friends."

2 "Please tell me you didn't just smell her hair. You're such a gibby!"

Ever since the weather got nice, that gibby has been doing nothing but playing frisbee and screaming "FOOTBALL!" all day on the green outside my window.
