ASF

ASF

An initialism for "age, sex, from," commonly used in Internet chat rooms to inquire about one's age, gender, and location. I remember everyone being so quick to ask "ASF?" whenever someone joined a chat room for the first time. Of course, you could never believe what they told you anyway.
