When I used to live in Texas I would go to the country bars and harrass the wannabe cowboys with their huge belt buckles, calling them tombstones for a dead dick would usually set them off.
STDiva's size assessment sounds pretty accurate, anything more and you better be entering the boxing, mma, or wrestling ring.
yes i have several belt buckles, they're normal sized and i wear one every day. those retarded and excessively huge ones are impractical, ugly and moronic though.
