Answer: WYA stands for “Where You At” and can be used to ask where somebody is physically located.

Asking where somebody is means that the speaker wants an answer about their current location. For example, if someone who has gone on vacation leaves his Facebook status as “en route”, then the people who want to reach him will know that he’s on his way back home or at least on the road, which saves them time in finding out what airport was left. They can say, “WYA?” and they’ll get a different answer than if they didn’t know what airport was left (in this case for example it might say San Diego). This helps save time by eliminating something unnecessary like figuring out coordinates of airports between where they are and home. It is an informal request that means “Where are you?”
