Uhmmm... Don't fucking tell them what your doing?
Dumbasses wont know the difference anyways. I don't let people do anything more than look at the computer screen with all of the nice colors. Don't bring up drumagog or any of that shit, just don't tell them if it's going to be like that. Do you let them watch you mix? That's gotta be awkward. "Uh... yea, im just uh... tuning your fucking shit voice and snapping your guitars to the grid cause you blow. And your drummer sucks bawls, shit can't even be edited." That should shut them up.
