Hubbinsd's Holiday Lassi

Description
If you have ever had a Mango Lassi at an Indian restaurant, here is the Irish version: A while back someone posted a link to their grandfather's holiday egg nog recipe. I made it last year and it was amazing. Very, very strong and super rich. So first make that, but any nog will do:

Ingredients

 * 2 parts egg nog (with rum & whiskey if it doesn't have it already)
 * 2 parts mango and/or papaya juice
 * 1 part rum (yes, MORE rum)

Directions
Mix well, serve with ice. Get smashed.
