"Ya me voy" is sometimes heard often; for example at the end of the workday. What alternative phrases convey a similar meaning? "Me marcho" comes to mind, but it seems to connote walking in formation.
I realise this is an open-ended question that may or may not have a good, single answer. As such if this is a poor fit for this particular site I would agree with closing/deleting the question. In either case, thanks very much for your time and I look forward to any answers.
