Time Pass, a word coined by the Mumbai junta which means to pass your time by anything and everything other than what you are supposed to do.
In a city which is always running, time pass means to stay in office beyond the hours just chit chatting in the name of work.
Or sleeping in the train while on or back from work.
The short form is TP karna.
Usage.. 'Chal TP karte hain'
It took me a while to get used to this lingo. What is the lingo that you got used to when you were in a new city?
