To work out in order to become extremely buff. A person who is really buff is "pamped".
So I was pamping the HARDEST yesterday. I looked at my sweaty muscs and thought they were fatty. After several hours I decided to leave the gym and went to my car. Right when I was about to climb in the door some hipster kid walked by and quietly whispered "pampy-pampy-pampy-pampy-pampy". I guess my muscs are the most pamped! its fatty! I feel the most musc!!!
