What does "callouts" mean? At 0:41 of this funny video, the man said "I'm loving these callouts." https://www.facebook.com/TheGamingBibleLB/videos/1211202768910363/ Does he refer to what the other gamer he's talking to say over the radio? I looked it up in the dictionary, and it means "summon" or "an invitation to fight." But how to explain?
