Seniority

Seniority is a term used to describe the number of years a team has spent debating together, or the age of the team members. A team which is older or has more experience is said to have seniority over a younger or less experienced team. It can also be used pejoratively, for example: Jay and Taylor suck, because they don't have seniority, but Tyson sucks more because he can't win anything.
