BG-Unit means "Bulgarian Unit." It is commonly used by Bulgarians who think they are awesome, thug, and cool like the actual members of G-Unit. However, the term was actually coined by two Americans, even though many Bulgarians refuse to believe this for fear that it might cause their masculinity to be questioned.
"DA JIVE VELIKA BULGARIA! BG-Unit!", said the Bulgarian, unaware that BG-Unit does not actually exist.
