I go through fazes with my drinks. I got so sick of vodka cranberry because it would usually be the only option besides beer at college parties, but it was the cheapest vodka in the world with warm, gross cranberry juice. That kind of turned me off the drink for life.
For a while I was hooked on White Russians. It was like having dessert and coffee! I also drank peach schnapps for a long time. Then I fell in love with Midori Sours. My college gives each class year a color, and ours was green, so of course we had to think up a drink that went with it! After about a year, I felt the Midori Sours were too sweet and not strong enough, so I started to order a flavored vodka with a spalsh of sprite. I find that sort of boring, though. I'm definitely on the hunt for a new drink so I'm glad this thread was created!
A really fun thing to make for casual parties is alcoholic milk shakes. Mix either vanilla or chocolate ice cream in a blender with peppermint schnapps, and pour! So easy, but so good.
