The sexual act whereby a person with a tracheostomy pipe performs fellatio on a second individual while a third party precedes to take a french fry and place it in the tracheostomy hole. As the second party ejaculates, mayonnaise is promptly dispensed onto the french fry and the condiment covered french fry is enjoyed by all involved.
A variation of this act is the New Orleans Ketchup Dispenser when the penetrating member has an STD and blood comes out instead of sperm.
I visited Robert in the ICU tonight, Sally found a mouldy french fry on the floor so the three of us had ourselves a New Orleans Mayo Dispenser.... if you know what I mean...
