Butterfart effect 

The butterfart effect is the idea that small things can have non-linear impacts on a complex system. One person farting can trigger another to do so as well. The concept is imagined with an individual farting in public and the unexpected socio-psychological consequences. Of course, a single act like the individual flapping its buttocks cannot cause a shitstorm.

Little did Phil know that his loud breaking of wind in the elevator had a butterfart effect on the whole office block. The place reeked for hours.
