I was in similar situation. Half of a month ago younger brother played in csgo (10 years) and asked me about how him can communicate with his friend. I've said him that he can use TeamSpeak and he ask "team.. what ?"Example:
Tom: "Charlie, want a TeamSpeak badge?"
Charlie: "What is TeamSpeak? Is that kind of like Discord or something..."
