mack daddies

Mack daddies is the plural of mack daddy, slang for a man who is conspicuously successful with women—a smooth-talking seducer or pimp.

The term emerged from Black American slang in the 1960s-70s and spread through hip-hop culture.

It can also mean someone who excels or dominates in any field: He's the mack daddy of used car sales.
