If a group of chicks are drinking beer and smoking cigars in practically an empty arena, dat ain't the same as em "celebrating in public" to me. Maybe if 20,000 people saw em celebrating in the arena, I could see the celebration being more in public then.
What's the big deal about the chicks' celebration? The playa who drank and she's only 18 years old...last time I checked, underage drinking is common in the USA as well. I hope she had a cigar with her beer. :)
