is a slang term for a rich man who offers support (typically financial and material) to a younger female companion in exchange for sex, friendship, etc.
Think sugar daddy, but with a whole lot more money. He's filthy rich, and can set you up with clothing accounts, overseas holidays (Dubai is the current hot destination) and sometimes even a car. So when you date one, your life has been blessed. Financially anyway...
Khayi: I'm so in love with my new man. He took me on a cruise, gives me money for clothes and groceries, and he finally agreed to buy me a new car. He's such a blesser.
Jez: No, Khanyi, he's not a blesser. You're just a gold digger.
