Time for Trevor to meet Barry!
Head to the same place Michael met Barry at. A scene will occur here and while Barry doesn't get Trevor's support (Trevor's more into, well... selling things illegally for profit), he will get him to take a toke.
This does something similar to what happened to Michael, as Trevor starts to see clowns. Killer clowns! Time to go on a rampage! You have an automatic shotgun here and will face clowns appearing out of purple mist from both directions. Kill them as fast as possible and stay on the move to minimize the damage you receive.
At one point clown vans will start to appear. When left alone these vans start to let clowns spawn indefinitely, so you must destroy them. Aim for the engine area to destroy them quickly (you can take one out in one shot with a well-placed engine shot in fact, or 3-5 rapid succession shots). Taking out the vans before they can generate more clowns is one of the gold medal requirements. Stay on the move and keep killing and you should be good. If you do find yourself taking too much damage you can always use the nearby pillars for cover.
