treenie 

Can mean anything you want it to. It can be used to replace words that you would get in trouble for.

Stop touching your treenie and get your treenie outside you fucking treenberg. (cock, ass, dipshit)

MCR teenie 

An MCR teenie is a person (girl or boy) who just likes the band for their popular songs like, Welcome To The Black Parade, Helena, Ghost Of You and I'm Not Okay (I Promise). They do NOT know the other songs and will become confused if they are asked about the first CD, BULLETS. Most teenies started around when REVENGE came out. Sadly, they have increased due to the release of The Black Parade. MCR teenies have therefore increased greatly. Most of them are also 'over night emos' and swear to know all about the band, while only know Gerard Way and 'his kid brother'. They have limited knowledge of Life On The Murder Scene and MCR's first demo.
Pretty much, a normal teenie. Just a bazillion times worse.

Fan: *playing MCR CD.*
MCR teenie: *overhears* OMG is that Helena?!
Fan: Yeah.... >->...
MCR teenie: *sings along*
*song ends, Give 'Em Hell Kid comes on *
MCR teenie: HEY! PUT MCR BACK ON!!!
Fan: *faceplam*

Treniece 

Treniece is a baddie. She doesn't take bullshit from anybody. Don't matter who it is, you, your mother, your mother's mother, It don't matter. She will always have her friends back no matter what. And she is a loyal girlfriend who will never ever leave her companion alone. Treniece is stubborn but for good reasons. Therefore she is the best.

"Oh my god, is that Treniece?"
"Yeah it is! She is so cool. But don't mess with her."

treenis 

Huge penis that can be mistaken for a tree, the kind of thing you see in modern porn. A penis so big you wonder how any mortal woman can take it.

Holy shit! That thing is huge! If your girl can take a treenis like that, she's ruined forever.

teenie 

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.
