hi! i'm from Argentina so i'll explain a little. the point of the game is to win a trip to Bariloche (a beautiful place in Argentina, tipically known for its mountains and cold weather) as a way to celebrate that you finished high school. we call it "Viaje de Egresados" (Graduation Trip) and every winter, high school students from around the country travel there (with no parents and in buses), you get to stay in a hotel with your classmates for a week, at night you get really drunk and go clubbing, and during the day you visit different places and do local activities. it's pretty cool but way too expensive! that's why they created this show, if you completed the dares you win a free trip for you and your whole class to Bariloche, with everything paid. hope that explains something :)
Finally I understand. My 3 years of high school spanish didn't do too much to help me. All i could understand was "accepto cortande tu pelo?" Thanks for clearing this up.
