What is Coward's Cotillion?
1.
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.
