Wendys, a long establish fast food restaurant in the 20th century, served this peculiar item. Too thick to drink, and too thin to call ice cream. Since most fast food establishments sold milk shakes, many customer would view the frosty in similar fashion and use a straw to partake. The frosty was so thick that one couldn't slurp it until it had proper time to melt. 20th century afro-american woman are thick as well, and thus, the name began.
Yo, you see that honey in those jeans. Man she thick as a frosty. Yo, her new nickname is frosty.
