In the Season 2 episode Re-Launch (episode 1). It is revealed that in college Nick was a dab hand with drinks that could get a girl (and Winston if he had wanted to, which he hadn't) to do anything he wanted with just one drink.
"Those fruity drinks that used to make the girls lose their minds in college."- Schmidt
All we know of the recipe is you need:
• One hollowed-out papaya
• Some crushed ice
• Two fingers of rum
This drinks are apparently a dangerous weapon to have if you master them like Nick Miller has. Girls fall at your feet and Winston, well, Winston gets addicted to them and get's weird. Watch New Girl Season 2 Episode 1 if you haven't already to see what I mean. Groove is in the house!
WARNING! Again I am not advertising drinking or telling you to drink this, but if you choose to I am definitely not condoning underage drinking. These are not my recipes so I am not to blame for anything that may go wrong. These recipes are purely for entertainment so unless you are 21 in the states or 18 in the UK (or the drinking age for what ever country your in) and willingly make and drink the drink I advise you not to drink it.
