A guy who thinks putting 'inho' on the end of his name is cool. In reality, it isn't. Jackinho is someone who isn't very popular and doesn't have any friends and really struggles to adapt to the realities of society and is often
friendzoned by girls who are convinced he is gay.
This is a guy would often write very poor poems about his emotions just to gain some form of
attention from people he doesn't know. He is very much life's own perfect loser.
