MBDI - My Brother did it.

The abbreviation given to the most common and uncreative excuse for ones actions while on the net.

The excuse will most commonly blame the younger brother and is used for just about any embarrassing or demeaning mistake, whether the regretful accuser has siblings or not.
e.g 1

Admin: Fail hacker is fail. Enjoy your ban.

Hacker: Oh sorry man I let my lil bro on my computer. He must somehow know the exact server I play and decided to hack on it.

Admin's response: Oh the old MBDI excuse? Next you'll be saying your cat got you banned!

e.g 2

girl: This e-relationship is over! I thought we were friends but it turns out your just a sleaze. Why did you try to cyber with me and send me pics of your cock last night you sad little boy.

boy: Who me? oh no.. that was my little brother on msn, I told him not to speak to any of my contacts!

girl's response: Don't pull that MBDI s*** on me!

Serial Monogamist 

Someone who jumps from one relationship immediately into another one.

Serial monogamists can not stand to be alone and often suffer from vast commitment and insecurity issues.

Because they jump into relationships immediately after the previous one has ended, serial monogamists typically don't take the time to reflect on their behavior or why their previous relationships failed; thus, they end up making the same relationship mistakes over and over again.
Person 1: Damn, Dustin already has a new girlfriend?! It's only been two weeks since he broke up with his fiance! I think he's a sociopath.

Person 2: No, he's a serial monogamist...
