"monkey nuts"Is only played when totally trollied.
The boys take down their pants and the girls close there eyes while feeling the a random guys balls.She has to say if it is or is not her partners balls etc..
If she gets it wrong she has to drink-if she gets it right the guy has to drink.
quite similar, its a challange game where the last one to down a pint has to drop thair pants and grab their tackle, pulling it upwards thus looking like the last chicken in tescos, and then run round the bar.
