Algernon

This is a situation where a person (normally female but it can happen to anybody) spends the night in a haunted house and has a consenting sexual experience with a ghost. This leaves the participate with a feeling of burning fire deep within their soul and shocks of ecstasy across the whole body. The phrase originates back to an incident that occurred in a turn of the century story The Woman's Ghost Story by Algernon Blackwood, hence doing an Algernon.

"Did you hear about Sally? She got a right Algernoning last night!" or you could change it to "She got algernoned" or

" Didn't you know? Sally had a visit from Algernon"
