when you’re taking a fatty shit and as you’re squeezing a little bit of air comes through in the sound of a whistle
i was going poop in the women’s room at the airport when i let out a loud booty whistle...
Letting out a fart that sounds like hum or whistle after taking a mean dump.
James: man my booty sore from that mean shit bruh
Joey: best not fart ole whistle booty head ahh
