how does football work for ucla games

heyyyooooo i'm in greek life at Cal here and super stoked for friday's game because gamedays are the best days. I understand that you guys do gamedays a bit differently here, could someone give me some insight to how they work? Do things happen at the frats or at the actual stadium (we just had our big game against stanford and they tailgated on this big grassy field vs we just rage at frats) so just wondering if you guys do the same kinda thing on the grass or tailgate at the frats? a few girls in my house are going to the game so we wanna get drunk first (because what is a football game sober lol) anyways much appreciated cheers to the best 2 UC's/Public Universities in America!!
