I'll start off by posting a word. The next person had to post an antonym of that word. The person after that had to post a synonym of the word before him/her. The person after that will start a new word that starts with the last letter of the last word. Use an online dictionary if you'd like

EX:
Person A:
Big
Person B:
Little
Person C:
Small
Person D:
Low
And then it repeats

Good Luck
