Physical violence... to kick or beat someone sooooooo hard and repeatedly that he is definetely going to suffer. O.o

beat = 1. hit; 2. be victorious over "Beat the crap out of" has two meanings: 1. Hit someone till there is nothing left; 2. Not understand a thing! e.g. Why did he do that? It beats the crap out of me. (I don't have a clue)

It means to beat up someone very hard, to pulverize them.
