look up any word, like pussy:
 
1.
Beyond the basic mac daddy, mac dad-day refers to the fellow who has gone beyond the basic pimp-lisciousness to an elevated level of cool.

Often seen cruising the streets of Chicago in any one of a collection of tricked out Cadillacs or a hot motrocycle such as the '09 Buell Ulysses XB12XT, the Mac Dad-day is the most stylish of men.
Shoo-la! That man is such a Mac Dad-day! He's so hot you don't see flames just a faint trail of smoke left behind!
