Used constantly in software development.
Person 1: We think the new functionality will really improve the user experience.
Person 2: *Bitch Slap* You mean you think they'll like the new changes?

Huge party last night girl! I did not think you would be in to work today. Say, why is your underwear overtop of your coat? And are those cereal boxes on your feet? You sure you are functional?

If you're from San Diego, you know what a function is.

For you outsides, a function is a kickback, party, where people be swanging, getting faded and fucked up. An infamous place for fights and drama.
Person 1: You going to the function tomorrow?
Person 2: Nawh, my girl don't like it when I go to functions, she don't trust me.
