This is an easy (and sometimes strange) one. Somebody gives a word, and the next person states the first word that pops into their head on reading it. The third person says what word they associate with that one, and so on.
For example:
1st person: operation
2nd person: hospital
3rd person: babies....
Let's begin with something seasonal:
snow
