Punishment for failing to answer a feat of strength when challenged by another man (generally at a bachelor
party or other like event).
The coward is required to take three
bull-
rider shots in a row (the cotillion).
Peter challenged Ross to an arm
wrestling contest and Ross was
scared he would lose so he rejected the challenge.
Ross is thus a coward and is required to complete the coward'
s cotillion as restitution for his cowardice.
