A shit talker is what 99% of people under25 years of age are, especially when around other "shit talkers" who like try try to impress other idiots of their age group, to try to appear "worldly" or "knowledgeable" about something they know absolutely nothing about. Shit talkers are silent around adults, (people over 35) because they realize that people who have lived a while have heard plenty of bullshit talk and are not impressed by juveniles babbling bullshit.
