The wha?

Today I learned what a three-point line on a basketball court is. We had a team bonding event throwing balls at each other and dodging them - dodgeball. We played on an indoor basketball court and throughout the game, the boundary lines would change according to the referee. At one point, the ref. said we could go all the way up to the three-point line. We all looked at each other not knowing which line he meant and continued running around as normal. He repeated himself and we were all like..."where's that?" CW, "C'mon, we're programmers..."
