It seems that everyone in Desi culture a painter and uses walls of public places like historical monuments, public toilets as their canvas. Wall chalking by the political parties is their right.
How do you see this practice?
Share some funny / nasty messages that you come across, while visiting these places.
let me start first:
On our way from Lahore to Islamabad, the bus stopped near a motel so that pessangers can relieve and have some snacks. When I went to the washroom, mere to 14 tabaq roshan hogae and my vocabulary for nasty terms increased a lot Out of those nasty message, one that I can share here is : ‘Yahan bade badon ki thandi nikal jati hai’
In Karachi bade hakeem saheb’s ads were part of many walls in different areas. The latest ad that is written on walls at the start of Lyari Expressway (near Sohrab Goth) is so explict that I can’t even make a hint about it
How about the historical places like Laal qila and Taaj mehal? Do people write on thewalls of these monuments?
Its not a desi practice only look at the works of Banksi. :D
I used to be a pretty contraversial street artist too most of the work is stencilled but once we did make a mural on a factory wall over 20 meters long depicting the strugles of various people across the world.
Well I suppose knowbody knows that but Banksy is a Famous street artist and one of his/her most mindblowing murals was in Gaza and another one on the Isreali Defence wall…
I am inclined to believe Banksy is a Woman and that many will know she uses special stencils for her artwork but you can buy some these days.
Out of those nasty message, one that I can share here is : ‘Yahan bade badon ki thandi nikal jati hai’ 
You mean non-desi are also involved in such activities.
So I’ve to google this Banksy
