English uses 'fart' as a verb directly, but Japanese usually uses noun+する (おならをする) or noun+出る (おならが出る). Avoid trying to conjugate 'fart' as a single verb; there is no exact equivalent.
おなら is the standard, polite enough for most situations. 屁 (へ) is crude and often used in set phrases like 屁をこく (to fart vulgarly) or 屁の河童 (a proverb). Use おなら unless you want to sound rough or humorous.
