When you're worried that if you fart you'll accidentally shit in your pants (aka draw mud).
"I never got sick in India, but there were definitely some patches where I wasn't farting with confidence!"
"They have an awesome chilli paste which on many occasions has stopped me farting with confidence."
Expression. Refers to the moment in time when someone has 'turned a corner' in their recovery from having 'loose motions' or diarrhea. No longer do they have fear of #sharting (soiling pants from farting) and are now able to 'fart...with confidence'.
Q. Are you still sick with diarrhea?
A. Nope. I'm back, 'farting with confidence'!
