All week we’ve been giving you some of the hottest girls dressing up for Halloween. From supermodels to the superchested, you should know by now that we deliver straight fire. COED Nation, today is no different. Since most of us celebrated the holiday last night, it’s only fair that we look back on the hottest Halloween backsides. Strictly spooking (yes, that happened) these butts are bewitching. Check ‘em out in the gallery after the jump!

There are certain essentials when Halloween comes creepin’ ’round: themed cocktails, girls in slutty costumes, and glow in the dark condoms. The biggest and best must-have is the posterior or ass. We’ve got quite the eye for backsides as you can see from our previous Ass-entials entries for the World Cup, Beach Volleyball, Lingerie Football, Surfing, and Pole Vaulting. However, we must say, THIS gallery is scary good. It’ll have you blastin’ Juvenile’s “Back That Ass Up”
