Karachi smells really weird right now and people on Twitter think they know why

It started off with a smell.

For the past few days Karachi residents have taken to social media to complain about a strange smell engulfing the city. Today both the Sindh Environmental Protection Agency and the the Pakistan Meteorological Department (MET) admitted they had no idea what could be causing the foul stench.

Which means Karachi's residents naturally turned to... Twitter for answers.

This guy says he knows. Better duck into your bunker!

Some think deodorant might solve the problem

Some people thought the threat was... homegrown

Some resorted to conspiracy theories

Some people got a little morbid

And then there's this guy, who spends wayyy too much time on social media

So that totally makes things clearer... right?
