A bloody used tampon wrapped in toilet paper that a dog digs out out of the bathroom trash and chews on it.

A rumburger is a pussy that stinks so bad that the only way you can eat it is if you pour rum on it. The rum acts as both a disinfectant and odor neutralizer.
That bitch was smokin but she had a serious rumburger.
