A subordinate insignificant male calls him self this to compensate for his small penis. Usually drives a pickup truck with a lift kit and oversized tires. Also has a larger than normal caliber handgun and or rifle. Often uses the term, "Who's your daddy?" and has a very cocky attitude. see also "phallic symbol".
Check out that bigdaddy in his monster truck packing a S&W 500....what a choad.
I knew that he was compensating for his micro-penis as soon as I saw him pull up in Bigfoot with a bumper sticker that read, "Who's yo daddy!"
