This is a gourmet selection from Wendy's, similar to a chocolate milkshake, a frosty is a landmark in a fatty's diet. It not only calms the fatass, but also gives him a sensation of joy that he will never get from anything but food itself, (i.e., a woman will never give him this exhiliration). A "Tall" Frosty however is a frosty that is relatively taller than a regular frosty, but subsequently, doesn't exist.
