look up any word, like darude - sandstorm:
The act of stimulating a woman's vaginal orifice with your fingers whiles shes passed out, blacked out, etc. etc.

most likely done at parties or other places women are taken advantage of.

if caught in the act of an Inacay you will probably be greeted with a slap, kick to the nuts, or sexual harassment lawsuit.

Popularized by the wrinkly Dean Inacay
" Did you hear that Bobby gave Susie the ol' Inacay?'

' i heard he got three fingers up there before she came to!'

" What does he get out of that...?"
