GMFBO! 

Sent via text, the acronym "GMFBO" stands for "Giggling My Fucking Balls Off" this acronym is a more vulgar version of saying LOL or LMFAO. This should be used by only men, transgenders or women who also happen to possess testicles

Helen: My parents are idiots! They think I'm going to the football game when I'm actually going whoring around with my slutty friends!

A shorthand version of the name Gary Motherf****** Oak. The name is used to represent a rival who one-ups you at every conceivable instance, as Gary Oak did to Ash (or as his counterpart did to the player character in Pokemon Red, Blue, Yellow, Fire Red, and Leaf Green).

You just defeated Lance, with only one pokemon left and no more revives. You're ready to be declared Champion, until Lance reveals that someone else has already beat him: GMFO.

GMFB 

Not to get confused with "fuck bitches, get money" that was originated from rapper Lil Wayne... Get Money Fuck Bitches came from 805 area code specifically in Santa Paula by two guys named Max Moreno and Roland Hernandez. GMFB means to literally get money first above all and fucking bitches second because no bitch is gonna have sex with you if you are broke.

you know just chillen, and GMFB'ing down here

GMFB 

A LIFESTYLE. A certain way to live. GET MONEY FUCK BITCHES, but not literally "fucking bitches". It means to forget about anybody that wants to hate on what you do.

I want to live a GMFB lifestyle and not worry about anybody that doesn't like what i do.
