The full form of SML is story of my life
This slang acronym is used most often in online chatting and text messaging to represent the phrase “screw my life” or “story of my life.” This is the typical response by someone based on their own negative experience and is typically used as a means of sarcasm and humor.

Origin of SML
The similar phrase “fu**my life” and the corresponding acronym “fml” became popular after a website was created by the same name. On this site, users were encouraged to share their fail stories that had happened to them ending with this phrase or a hashtag of the acronym. This phrase then became popularly used on all social media for the same purpose. Shortly after, some users who didn’t like the extreme profanity of using the “F” word used the synonymous phrase “screw my life” and its corresponding acronym to express the same feeling. However, this is also considered a form of profanity for some so users also began using the less colorful phrase “story of my life” sarcastically to represent the same thought.

Other Meanings
As is the case with almost all acronyms, this one can also be used to represent other things as well from random phrases and words to official titles of businesses and job-related practices. Some other things that this acronym can be used to represent are “Small, Medium, and Large,” “Self-Managed Learning,” “Semantic Markup Language,” “Super Mario Land,” “So Much Love,” and “Secondary Mortgage Lender.” This is not an all-inclusive list as there are simply too many possibilities of what this acronym is used to represent to list them all here.
