Why did they pee on the suitcases in the car???
In the scene where Marcos goes to meet Ana before their 'date', he waits for her outside her house. She returns from what presumably was a late night, in a car with some drunk guys, other girls and a couple of what look like 9 year olds(!?)
When the guys get out, before they go in the house they go to the back if the car and piss all over the suitcases in the boot/trunk, to the apparent delight of their young companions.
Q: WTF???
