In chat, ASL stands for Age, Sex and Location.
The rise of the digital age has many benefits; however it has led to physical isolation. This pushes many people to withdraw into the digital age and seek company online. This has led to the rise of chatting online with strangers.
While chatting, it is often common to ask the stranger for their Age, Sex and Location, commonly abbreviated as ASL. Depending on the manner, this request can come across as rude, especially if asked first and without a proper introduction.
ASL is also commonly stated as ALS (Age, Location, Sex).
