1. The act of everyone in the vicinity of an odour of anal origin (OOAO) denying culpability.

2. Smelling a fart in a room/area where one is alone; yet not remembering the sensation of passing any gas.
'Everyone denied that the smell originated with them. Someone must be suffering from Fartnesia!'

'I was in my room when a foul odour of ass gas came across me but I dont remember farting- is there a plate of cheese under my bed or do I have Fartnesia?'
