verb. (past tense)

To teenie: To act like a teenie. Most likely jumping up and down and squealing, often waving hands around. Can also involve hugging and/or dancing. Imagine a teenie being told their object of affection (famous person) is coming to their house. Yeah, like that.

Someone that doesn't give a damn about the music that a band makes, but only like them for the fact that they're "h4wt" and "everyone else likes them". They would be lucky if they even know the names of the people that they are referring to as "h4wt". Teenies tend to write in an unbelievably retarded way as well.
example of teenie writing: OMFG!!1! D1D U LYKE C PETE WENTZZZ???!?!?! H3S LYK3 S0000000 UNB3LIVBLY H4WT!!! I WANNA MRRY H1M ND AVE HIZ BUHBEEEZ!!1!!11!!!!!

note the excessive use of exclamation marks and abbreviations. this is a classic example of teenie writing.

annoying little people who decide a band is worthy of their time based on how much they want to get into the lead singers pants. They then bitch on said singer's spouse claiming that they are 'stealing there man', etc.
If they have gotten to the obsessive stages, they may even take to giving they're "beloved"'s pet names, carrying little pictures in their wallets... etc.
Teenies are astonishingly shallow creatures as they can manage all this without actually buying a single/album. And even if they did it would be to stroke the cover.
teenie girl: OMFG how dar he lyk av a wife he iz my babeh!!!! we r ment 2 av babies togeva iv named em aftr me n him and evrythin oh THAT BITCH! F*CK HER!! *voodoo*

more intelligent teenie: Oh get a grip. So what if he has a wife? You have to learn the art of seduction, we just need his address. Look, you're not even doing it right. Stick it in the puppets stomach! Fool!
