Emfartsis 

Deliberately emphasising the noise made by a fart in order to heighten the sense of amusement or disgust surrounding it.

I farted so loud it had emfartsis

Emfartsis 

When you make a statement and fart (release gas) audibly so as to emphasise the point.

A smelly stamp of approval as it were.

Wife: No honey, my afternoon is bonkers so I need you to pick up the kids!! (Loud fart Emirates)
Husband: Well with that emfartsis, I’ll have to do it.
