One Piece Chapter 40, page 3-4: USOPP PIRATE GROUP

Luffy stands tall over the defeated Kuro and proudly declares his name: "MONKEY D. LUFFY!!!" He looks down at Kuro and says, "THERE'S NO WAY I'D LOSE TO A PIRATE WHO GIVES UP HIS NAME AND RUNS FROM THE SEA. THE ONLY TIME A PIRATE SHOULD GIVE UP HIS NAME IS WHEN HE DIES!! YOU BETTER TRY TO REMEMBER MY NAME..." Jango and the other pirates sweat in fear, whispering, "LU... LUFFY...? I'VE NEVER HEARD OF HIM". Luffy then smiles widely and proclaims, "I'M THE ONE WHO'S GOING TO BECOME... THE PIRATE KING!!!

Panicked, Jango orders his crew, "TAKE HIM BACK!" The Black Cat Pirates quickly pick up the unconscious Kuro and run back toward their ship, muttering, "IS THIS GUY.... CRAZY?" and screaming "AAAAARRRRGGGGGHHHH!!!" Jango runs alongside them, shouting back at Luffy, "...AND DON'T EVER COME BACK!!!" Once they are gone, Luffy stands alone, breathing heavily with "HUF HUF..." and dripping sweat and blood as the adrenaline fades.
