A lot of people on this page think this term has the same meaning as "mud shark", whereas they're two separate but closely related terms. A "snow bunny" is a curvy, thick-bottomed white chick that black men would be interested in. A "mud shark" is a white chick who actively seeks out the attention and partnership of said black men, usually never getting it. These two phrases are easily confused, but they aren't synonymous. Know the difference.
