debauch; 1) to corrupt morally with shameless seducing. 2) a period of intemperance and self indulgence. When Harry meets Gabriella, he thought she would be just like the rest; easy, quick, meaningless. But Gabriella was different; her mind was already corrupted and unchaste. It angered Harry so, he swore to himself that he would mess her up even more then she already was. He would destroy if he had to.
