it's two ones that are big in the meta rn.
Give me my money
This started off as one person telling a second 'give me my money [bitch].' while everyone surrounding went 'ayyyy', but the concept of 'ayyy', 3 distinct roles, and all words except 'give me money' have since been deprecated or were too hard to explain. Now, the kids stand in a circle and very sweetly take turns saying 'give me (my) money' and then everyone cheers 'yay!'. Play continues around the circle until some number of players lose interest. There must be at least 4 players.
Clean my Toilet
One player makes a disguised 'toilet' with their hands by placing a closed hand over their other fist. This player entreats the other player 'open my hand' followed by some amount of protestation by the other player. Once the hand is opened, player one says 'now put your finger in.' followed by another round of negotiation and protestation. Eventually the second player sticks their finger in. The first player then says 'thank you for cleaning my toilet!' and sometimes teases the other player for 'cleaning their toilet'
Amazing
