Made famous by TV show, The League (FX).

Rosterbation: The near pornographic pleasure derived from over-excited interaction with a sports team's squad roster.

While can be relating to a real team, as in a fan rosterbating to their professional teams lineup, it usually refers to the narcissistic pleasure of rosterbating to a line-up created by the rosterbator. Examples include a fantasy league team, or a video game career mode team.
I can't stop rosterbating over our lineup this weekend.
