YayDubs's definitions
The itchy aftereffect of a deep and cavernous fart that reverberates against objects such as furniture or flooring, resulting in an itchy anus because of the heat and friction generated by the violent release of gas.
"Bro, last night when I was leaning against the wall at the club an itchy steamboat snuck up on me...I was scratching my b-hole for the rest of the night. Shouldn't have mixed beer and curry, I guess."
