Roll?

When you're in game x and the brush calls you for game y, and asks if you'd like a "roll", what the hell does that mean? I'm too embarressed to ask.

My first guess is that they are offering to let you stay in your present game and "roll" your name back to the bottom of the Game Y list, in case you want in the game later....

Where did you hear this at? Regulars at whatever cardroom it is should be able to confirm...
