You will need at least 5 people to play. If you have more than 25 people, it may be good to split them in to two groups. First have everyone shake each others hand and introduce themselves to each other. Then have everyone stand in a circle.
Everyone will look down at their feet. When the leader yells “SCREAMING TOES” everyone will look up and look at one other person. They should have this person in mind before the leader yells “SCREAMING TOES”. If the person they are looking at is not looking at them, then they say nothing. If the person they are looking at is looking at them also, then the first person to yell the first name of the other person wins and the other person is out. Play until you are down to two people and both of those people are the winners.
