Here is the Urban Dictionary's thought of Jack: A character from Torchwood and some episodes of Doctor who. He is played by John Barrowman. He often fights Aliens from outer space. He has the inability to die, yet still ages. Some theories suggest that he is the younger version of The Face Of Boe.  Captain Jack Harkness can kick Captain Jack Sparrows ass! 
Wow, nice definition! :3
