this game can be played at any moment. the rule is if a friend sais that he will do something,for example "tonight I am gonna get of with 3 girls at once" then you can call "robocop", now your friend will have to do it in the time he said he would or drink 0.5litres of beer in one gulp. you can not call robocop when: he\ she does not say until when they do this thing. Thanks for reading here are a few robocops that i have had to do over the years; drink two bottles of vodka in 24 hours give a girl a cock's slap run down a highstreet and shouting at car drivers drunk and many more.
