rectum spectre 

Unknown anal activity. Not knowing or remembering if you had anal sex last night

I heard the door slam and woke up. James had left and my bum felt funny. Did he chuck it up my arse last night? Or was it a rectum Spectre?

rectum spectrum 

The range of frequencies one's rectum emits after massive ingestion of pickled elder gnome scrotums. However, one must be doted with the capacity of anal intrudership to qualify for rectal wavelength emission.

Ah shit, it's Lothario. That guy's such an arrogant, anal intruding piece of shit... What? Did you say he frequently ingests massive amounts of pickled elder scrotums? That guy's rectum must emit enough radiation to turn your face into the ass of a maggot. (rectum spectrum)
