A joke shared by my sister and I made a graphic out of it. 

I heard RJ Naved's Murga of "Are you Puri?". So this is inspired from that only. !

I don't know what's your reason but what I found most people do it for attention seeking only. !

Na Santoor Sabun, Na Fair & Lovely... I think these type of comments on girls' posts on Facebook makes them more beautiful. May be it brings a different type of confidence in them or whatever. ! :D
