The rules of tlab are quite complicated, and would take nearly an hour to fully explain. However, there are a few quick things to say. The sport is played on a tlab octagon with 7 players on each team. (some good fields are found in Minnesota and Romania). The ball is called a tlab ball, and the players are just tlab players.
Person 2: Tlab?
Person 1: yeah, man! Tlab! it's one of the more fun sports. I'll explain the rules to you while we're on the plane to Minnesota.
Mainly used in the context of chasing women. Most appropriate when the subject being chased is not at all interested.
Do you think she'll be up for it? She will if I T-LAB hard enough.
