Answer: This is billiard cue, if a guy doesn't know about this tool, it proves he is obedient.

This is a billiard cue, a tool specifically designed for playing billiards or pool. Its purpose is to strike the balls on the table with precision to achieve desired outcomes in the game. The statement suggests that if someone doesn’t recognize this tool, it implies they might not frequent places like billiard halls or engage in such leisure activities. This could be interpreted as a sign of obedience, perhaps indicating that the person spends their time in environments or activities considered more disciplined or structured, rather than in recreational or potentially less formal settings. It humorously connects knowledge of the cue stick to one's lifestyle or habits.
