Rock, Paper, Scissors

I understand that Scissors can beat Paper, and I get how Rock can beat Scissors, but there's no fucking way Paper can beat Rock. Is Paper supposed to magically wrap around Rock leaving it immobile? Why the hell can't paper do this to scissors? Paper can't beat anybody, a rock would tear that shit up in 2 seconds. When I play rock/ paper/ scissors, I always choose rock. Then when somebody claims to have beaten me with their paper I can punch them in the face with my already clenched fist and say, oh I'm sorry, I thought paper would protect you...asshole
