8. The I've-got-a-girl-at-home guy.
Married-man Howard from The Big Bang Theory is going to be that guy attached to his phone all night, compulsively calling and texting his sweetie. We all know that guy—the one who feels compelled to constantly check in with a lady back home. Good luck trying to get this fella to enjoy his evening out with the guys. On the plus side, he can save your table while you hit the dancefloor. Not a total loss.
