A chance to visit a place probably/hopefully unique in the whole universe.

This curious word refers to anything overly big - heavy and cumbersome in a dismissive context thus it's application is highly subjective.

It may also imply something technologically outdated due to the characteristics above.

 

Thus if your neighbour's foridon (mobile phone or mobile) is a slightly earlier model than yours it is a dangalaka despite the difference of only 10 grams.
On the other hand, no matter how weighty or cumbersome, a thiplowgambinon is not a dangalaka as under such circumstances, "big is beautiful" unless you can no longer affore the fuel bills for the thing and then - at least in private - it is indeed a dangalaka after all.
Thus we see dangalaka is applied only when embellishing to the point of hyperbole, hence antique earrings may be dangalakes (pl.) if they are not yours, but your divorcedand childless neighbour's twelve-bedroom middle eastern oil-magnate style spidi (house) is not, regardless of the logic involved.
