Zima was a great mixer as it had a slight citrus taste but nothing too heavy to overpower other things, kind of an alcoholic store-brand Sprite. We used to put shots of flavored rum in it. Straight it was just, meh. It did cause a wicked hangover if you did too many, probably from the mass amounts of sugar it had to have in it, so it was more the thing you drank with the food before the real drinking started for us.
Honestly, I wouldn't mind some for old times sake. Couple of those with some Malibu rum thrown in while eating burgers and pub fries then start on the pitchers of Killian's Red while shooting pool and throwing darts sounds like a good time right now.
