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.

lifting the sierra

Partying to the fullest. Usually after several drinks. To continue drinking or start drinking! To get real drunk but not to the point that you pass out. To drink; many number of alcoholic beverages and can also be in a short period of time. Feeling really good after having shots of alcohol.

Nick just pounds three beers in a row, I think he's going to lift the sierra.

John will be lifting the sierra tonight...

Sierra Bravo

Phonetic speaking of the letters SB, used to mean Shitbag. Spoken often in the presence of shitbags so that said shitbags do not realize that they are being called out.

Commonly used in the military, e.g. Navy, to refer to those who lack the ability to show any discipline, bearing, character, honor, care, or commitment to the fact that they themselves are a member of the Armed Forces.

1. That Sierra Bravo hasn't cared to iron his uniform since boot camp.

2. Our LPO is always pissed at this division because of all these Sierra Bravo's in it.

3. FN Kaine
