The typical punjabi male image of a sturdy male in kurta chadra holding a gandasa in his hand , and twisting his mustaches comes to mind when we hear that word.
But apart from an ugly looking attire and a sexual one (its all open down there LOL) , it just like its lungi cousin is quite vulgar .
I don't think it even conforms to sikhi ideals. I was originally worn by mughals. Surprising, sikhs adopted it
Kachhera doesn't even go up the thighs . So it was always meant to avoid unwanted flash LOL.
