@Clifton_CatsBy90What lot is best depends on what you're looking for. First of all, ignore lots 8-10, as USF only fills those lots when a big name (UF, FSU, Etc.) is in town. The lots on the South side of the stadium (lots 5-7) typically have more families and less of the rowdy crowd I believe you are looking for. The lots on the North side of the stadium (lots 1-4) typically have more students and recent alumni that are prone to being more rowdy. The USF student section is on the north side of the stadium and they offer free parking for students that carpool in lot 4, so that is the side the majority of students will park on.
That being said, since it is a Friday evening game, I do not know what the tailgating scene will look like. Those of us who are serious about tailgating will most likely just be getting off work when the stadium gates open. I like to imagine that I have one of the most rowdy tailgating groups (and 100% the loudest) but I don't even plan on tailgating this week because of the game time. Students should be mostly unaffected though, so lot 4 shouldn't see too much variation from a normal gameday.
TLDR: Park in lot 4 if you're looking for a rowdier crowd. Park in lot 6 if you're looking to chill.
