The phrase "what you do where you were" is a bit unclear, but it could relate to questions about actions done at a certain place or time. To clarify similar English usage:
- "Where were you?" asks about a specific place someone was at a particular moment in the past. It focuses on location at a specific point in time.
- "What were you doing?" asks about the activity someone was engaged in at a specific time.
- Together, someone might ask, "What were you doing where you were?" to inquire about what activity was happening at the place being referred to.
The phrase "Where were you?" is used for asking about location at a past time, for example: "Where were you this morning?" whereas "Where have you been?" implies asking about a period of time up to now and can mean what someone has been doing during that time.
If your question is from a song lyric like "What you doin'? Where you at?" from Bruno Mars' "Leave the Door Open," it is a casual way to ask what someone is doing and where they are right now.
If you want a more specific explanation or context please clarify your question.
