Soul farting is when one stares another in the eyes (soulfully, as it were) and farts. Usually
done to insult or catch the latter
party by surprise.
"Van peered deeply into Spencer's eyes wistfully, Spencer confused, returned his gaze. After several seconds of this, Van let out a
deep, wet sounding
fart. The smell was so terrible that Spencer gagged. Needless to say, Spencer was pissed."
