This term is more commonly used to describe disparagingly persons from a rural background rather than the urban areas and so most likely from the eastern end of Cyprus.
The word horkados (Horko – a village) is a synonym although a little more pointed and cannot be used as an affectionately humorous reference to a person's origins..
Use either with discretion, however, as it is best to avoid insulting people in Cyprus by suggesting they are unsophisticated lest they try to run you over with their thiplowgambina (non-accidentally this time).
It is wise to be cautious especially since the difference between the gouloufi (pl.) and their more sophisticated townie cousins are sometimes subtle.
Or indeed indistinguishable.
