Game played by homosexual or confused young men, usually at boarding skool's such as Trinity Grammer or Kings.
3 or more people stand in a circle around a SAO(a square Australian biscuit) and wank. The aim is to not be the last person who deposits their load on the biscuit, as they must eat the sperm soiled 'Soggy Sao'.
"Man those little bitches play 'Soggy Sao', fuck that! How can you eat a sperm covered biscuit?"
