Head to your school to meet with Mr. Mackie in the counselor’s office. There’s also a fast-travel point outside the school so make sure to activate that as well. There are three free selfie partners in the lobby of the school so make sure to take a selfie with them to increase your follower count in Coonstagram. Once you’re in the counselor’s office, sit in the chair and select your Sex/Gender.
Leave the school and you’ll be attacked by filthy rednecks outside school. This is a fairly straightforward battle and shouldn’t be that hard. The back of the truck can be used to deal knockback combo damage if you manage to push an enemy towards it. The redneck sniper is a soft enemy so you should be able to deal with him easily. After winning the battle, the mission will be complete.
