Knee Jerk by Purge Reviews

About Knee Jerk, from BoardGameGeek:

Think fast as the first player in Knee Jerk to give their knee-jerk reaction wins the point! Players rapidly create endings to funny situations in this 4-8 player party game. Each situation lasts ten seconds, and players get to play simultaneously (i.e. no downtime!). One player plays as the host, rapidly choosing and announcing situations. The first player to create a valid ending to the situation wins the point. If more than one player answers, the host picks his favorite. The first player to gain three points is the winner!
