a weird sensation in your buttocks where it feels like your stomachs rumbling but it is actually your butt.
person 1: hmmm, luce? i've got a bad case of the butt rumbles.

A unexpected flatulence that typically causes a massive rumble between ones buttocks while trying to hide it from his or her partner.
When I butt rumble in my sleep, my wife wakes up and beats me.
