look up any word, like cleveland steamer:
 
1.
The act of a man having sex with three women at the same time, while one of each of the women has blonde, brunette, or red hair. The blonde may be replaced with a geriatric white-haired woman as well. The involvement of a black girl instead of a brunette is a Dirty Neapolitan.
The wife was hesitant for me to bring in another brunette for a threesome, so we went with a blonde and a redhead and I executed The Neapolitan.

3.
To start, you must find a drunk slut on her period. you then must do her in the ass, making sure to get a good amount of shit on your dick. Then slip the dick into her pussy for a bit, getting some nice blood on it. Then put your dick in her mouth and blast a major cumload inside her mouth. If done properly, when she opens her mouth you should be able to see Brown, Red, and White, the colors of Neapolitan Ice Cream.
Dude, I found this horny slut last night who asked for the Neapolitan!
