Big Fucking German. Used to describe a German of large stature, whose size comes in handy when decimating his opponents. You can recognize a BFG when they get drunk and want to wrestle. However, BFG's are not always violent, since they also wear pink polos, listen to classical music, and enjoy long walks at sunset.
Holy shit man, did you see Peter fighting in the club last night? I thought he was so chill since he asked Bertha on that sunset date. He must be a BFG!
