<<Is this a totally incorrect usage?>>

It's certainly novel--and perhaps even charming (so that death by torture would indeed seem appropriate, jimthedog). "He thinks he has me in his pocket, but I'll be out of [his] pocket for a week or two [doing what I want, expensing up his expense account]." Or perhaps the reference is to billards/cubicles. And I think Mandy (welcome, Mandy) is on to something big where she mentions vacations.

Anyway, what is totally incorrect usage where it concerns colloquialism?
