Notes: For a shortcut, you can use pressurized whipping cream; squirt 1 cup of it into the mocha nog, then squirt more onto servings.
In a bowl, with a mixer at high speed, whip cream until it holds soft peaks (see notes).
In another bowl, whisk chocolate milk, rum, Kahlua, Frangelico, ice, and about 2/3 of the whipped cream until blended. Pour into tall glasses.
Spoon remaining cream in puffs onto drinks and sprinkle with chocolate curls.
