"Tsimboukas" - Tzortopoulos - Katoomba.

The parachoukli for Dimitri Tzortzopoulos - village of origin, Karavas - who may have been the same Dimitri Tzortzopoulos of Roxy Cafe, Katoomba fame - was "Tsimboukas".

I am unaware how the nickname originated.

Again, perhaps descendants who know of/still use the parachoukli "Tsimboukas" can enlighten us as to its origin.
