idk, my bff jill

A funny quote from a cell phone service provider commercial (that probably doesn't work, but their advertisers know how to do a good job) after a mother asking their young daughter why the texting bill is so expensive. It's a common way to answer annoying questions to Myspace surveys or generally obnoxious questions

Annoying girl says, "So, who do you have a crush on?"
Response, "Idk, my bff jill."

Big Friendly Idiot, like the old story of Big Friendly Giant.

Til I talk to my lawyer, you get no reply

BFG

people who relentlessly party and go out and work towards/achieve nothing in their life. They end up being complete nobodies in the real world but are too blinded by it because they think partying and going out is what matters in life

I am working the 9-5 job in my hometown and I achieved nothing in my life because I was bfg in my younger years.
