Quite the cotillion... (48.55)

Bobby: Tonight's a big one for me. The most important managers in the business will be there. Between them, they cover all the meaningful strategies currently in play.

Taylor: Quite the cotillion.

Bobby: It's the social event of the season.

The cotillion (also cotillon or "French country dance") is a social dance, popular in 18th-century Europe and America. Originally for four couples in square formation, it was a courtly version of an English country dance, the forerunner of the quadrille and, in the United States, the square dance. 

It was for some fifty years regarded as an ideal finale to a ball but was eclipsed in the early 19th century by the quadrille. It became so elaborate that it was sometimes presented as a concert dance performed by trained and rehearsed dancers. The later "German" cotillion included more couples as well as plays and games.
