I am throwing my boyfriend a surprise birthday party and need some ideas for mixed drinks.?

My boyfriend will be turning 23 here soon and I decided to invite some of his old friends back from home to surprise him for his birthday. There will be about 12 guests (mostly guys). Everyone is bringing beer and I decided I would like to serve a mixed drink. I do not like the taste of strong alcohol and would like something fruity. I usually drink flavored smirnoff wine coolers just to give you an idea of what i like. Thanks for your help!
