Mars square Mercury makes the mind combative. Thoughts move fast but they collide with each other and with other people's ideas.
Arguments are likely. Not necessarily destructive ones but the kind where both sides dig in and neither wants to concede. Your thinking is sharp but it lacks the diplomatic filter that prevents directness from becoming bluntness.
The square can be useful for cutting through nonsense and getting to the point but it is not useful for conversations that require tact. Save the sensitive discussions for another day.
What you might notice: Arguments that escalate quickly. Impatience with unclear communication. Writing or speaking with more edge than intended. Mental restlessness that resists focused work.
