Since it's not a technical term, it doesn't have a technical
definition.
The problem is that the "random" in random sample refers to the
process that generated the sample whereas, as I hear it used in
common parlance, the "representative" in representative sample seems
to refer to the specific sample that was obtained as a result of the
(possibly nonprobabilistic) sampling procedure.
