an extract from Shameless - "Top hat and tails? On your way, I'll look like an overdressed undertaker!" What does "on your way" mean? Get lost or something?
I would say from the context, yes! "Get lost" or any other (potentially ruder) version of the same.
It's a very informal, almost common (common as in the opposite of posh, not common as in regularly used!) expression, and is sometimes written as "On yer way" to give the pronunciation of "your" as "yer". Also sometimes said as "On yer bike".
