Sierra Mike

Slang code word for “Single Mother” utilizing the NATO Phonetic Alphabet (Used by the U.S. Military as well as others) equivalents for the initialism S.M. Although the initialism bares similarity to the slang term “MILF” (Not to be confused with the Filipino militant Islamic group “Moro Islamic Liberation Front”), MILFs were more in the context of being older than the identifier such as the mother of a peer or friend (as in the 1999 American Pop culture classic “American Pie”, which brought further attention to the term “MILF”). Sierra Mikes (Single Mothers/Moms) are characterized, more so, as being younger, roughly the same age or younger, as the person making identification. Both Sierra Mikes and MILFs can be attractive and desirable given circumstances.

Sierra

Sierra is the most outgoing yet sophisticated person you will ever meet. She may be insecure, but she is really beautiful. She is the best friend you will ever meet and loves to go to events. She sometimes looks down on herself but when she deos she just picks herself back up again. Overall she is the best person you will ever meet.
