your pocket in terms of Bass at least is your Groove, you've got a good groove going you want it to lock in, you want your playing approach to be in sync with the other music going on arround you in terms of how soft or hard your playing, fast or slow, how you're articulating what you're playing etc and having it locked in tightly with the rest of the composition of sound. Once all the screws are tight and you've got it locked in your 'in the pocket' to be deep in the pocket would be something i'd say about a particularly good bassist, someone whose immaculately set in the groove and at the same time has enough feel in what they're playing to have the sound of the bass tickling your balls with every bar. That's when you're deep in the pocket =)
