Think of a word and then link it to other words for example:
When me and henry talk we are BEMHEM
BEMHEM = HEN = CHICKEN = EGG = DINOSAUR = DEAD = SADDAM = GUNS = ROBBERY = MONEY = SEX SEX SEX WOO GO SEX
I finished with Sex so Henry continues with Sex:
SEX = BABIES = CHILD SUPPORT = COURT = CRIMINALS = JAIL = ANAL RAPE = BLACK GUY = FIDDY CENT = 1 DOLLAR = MONEY = SEX!!!!!!!!!!!!
So again it has finished in sex so the next person must do the same but with different words
