Cement Mixer Drinking Game
This is basically a shooter turned into a game. All it really takes is a bunch of people with strong stomachs.
Also, each person needs:
1 1/4 oz. Irish Cream Liqueur
1/4 oz. Rose's Lime Juice
Place Irish Cream in mouth, hold in place. Add Rose's Lime Juice, then mix in mouth by shaking your head "no no no" very rapidly. Mixture turns the consistency of cottage cheese, and not very tasty.
The last person shaking their head (without swallowing -- not that you'd want to) wins.
