fartastic 

When you fart very loudly and get a great sense of relief, as the pressure from the gut is released through a great fart.

Aah, that was fartastic, I can relax again now.

One who has mastered the art…of fart

“Gus’ farts are amazing!”
“You think so? I think Gus is a dilettante when it comes to farting. If you give him a bowl of chili it can be impressive. But Meep, he’s a real fartiste. I've wept from the beauty of his farts."
