Ashwin : I farted

Josh : You nasty F*ck ! Your insides must be deteriorating and rotting to produce a foul smell like this.What the hell did you eat !? *farts*

Ashwin : =.='''

Josh : I farted too..Oooh the aroma, the texture, the profound nature of it all, this is the art of a genius encapsulated in gas
