Chapter 3 (Preparation), in the trailer park where the chapter starts (Chapter Select: Preparation – Reunion). Let the same player do all three steps.

Walk down the trailer park to a woman sitting outside her trailer with a baseball bat. Talk to her: she's looking for her cheating husband.
Go to the nearby silver trailer with noises coming from inside and knock. The husband answers and slams the door.
Go back to the woman and tell her where he is. She heads over to his trailer, and the trophy unlocks for both of you.

Watch out
