Simply translated as "My cello of death", Mon Cello Morte refers to an anal gas leak characterised by a long, deep resonation with a slight rising pitch and garnished with a violent odour. The term initially derives from the uncanny resemblence to the sound of a cello being played slowly and with a single, deep note see Mon Cello. "Mon Cello Morte", however, may only be applied to a gas leak as described above, coupled with an extraordinary smell that invokes the involuntary reaction of vomiting.

A person with an outwardly dominant, masculine, or aggressive personality, but who also enthusiastically takes on the submissive or "bottom" role in the bedroom.
