A rippling occurs when a young lady is being serviced doggie style with wild abandon - the rhythmic pounding on her sweet, lush posterior sends ripples up her torso. These ripples terminate their journey in her face, producing a characteristic, cheek waddling expression of joy and fear - the rippling.
A fart so loud and powerful that not only will you worry if you've sharted, but the shock waves created by the booming sound, will ripple the skin along your taint.
Peggy Sue got the shock of her life. With Pete going down on her after their meal of chilli with beans, she let rip with what Pete later described as a taint-rippling fart. He could see the skin of her taint ripple with the explosion emanating from her arse.
Rumpling is the art of shaking, then smashing a beer can into ones own skull until it erupts. The rumpler then pours the beer down his throat like the blood of his enemies. Most commonly occurs at fraternalgatherings and when that really sick EDM beat drops. May lead to concussions or you just looking plain bad ass.
