A Game Where you cuff Your Hand and Your Enemys Hands into One, both Lifting Your Thumbs And say '1,2,3,4, i declare a thumb War!!'(maybe something other) and try to pin the enemys Thumb under yours. You may only use 1 hand. the winner who pins his enemys thumb down for a short time(5-10 seconds) wins the so called war.
