BG

you know how you play "slug bug what color" when your extremely bored or if you just want to hit your friend, BG is a similar game in which you most commonly use in church to identify a BG or Bald Guy them following with a punch to the shoulder toward his friend.
Other words may be:
FG- Fat Guy
UG- Ugly Guy
SG- Stupid Guy
RG- Retarded Guy
HG- Hairy Guy
MG - Mutated Guy

and so on

person 1:BG (following with a punch toward his friend)
person 2:WHAT THE HECK!??

BG

An abbreviation of the website becomegorgeous.com. (A website with makeup and fashion tips. Mostly for girls and a few gay guys) This is used because although the website is amazing, the name is not. the name is actually pretty embarrassing. Saying BG instead of Become Gorgeous is faster, and less embarrassing.

EMBARRASSING -

Girl 2 - nothing, on BecomeGorgeous!

NOT EMBARRASSING -
Girl 1 - whats up?
Girl 2 - nothing, on BG!

BG

Possibly an abbreviation of the BeeGees, a popular 70's group of 3 brothers. In fact, the BeeGees come from B.G. - Brothers Gibb. Well known for 'Stayn' Alive,' also 'Jive Talkin'' and 'How Deep is Your Love?' Integral in the phenomenally popular soundtrack from "Saturday Night Fever."

Saturday Night Fever is in fact the most popular movie soundtrack in history, featuring many tracks by the BG's.
