Flatulence
Gas, Fart
noun
The kanji and the word are exactly the same. That means they share meanings as well.
You learned this reading with the kanji, but here's an extra mnemonic just in case:
How do you read flatulence? Heh(へ)...heh..heh..heheheh. You can't NOT laugh at the word flatulence.
As with the kanji, some dictionaries incorrectly list おなら as a reading for this word, because the meaning is the same.
あなたは屁の話をしていると思っているんですが、合ってますかね。
I'm assuming you are talking about flatulence, am I correct?

それらの屁はまあ満足のいくものだったね。
Those farts were pretty satisfying.
