Acronym standing for "My life sucks a**." A chronic equivalent to the more acutely used "FML" acronym, denoting long term hopelessness pertaining to one's aspirations, outlook on life, etc.
Note: Although not completely synonymous with MLIA, also not mutually exclusive. Precursory to the more transitory YOLO, which accompanies more spontaneous acts uncharacteristic of the FML user with the intention of breaking out of the MLSA mindset.
Gonna be in Boyne the next few days for an expo of sorts, MLSA.
