Their Favorite Sports Team
Though cheering for a sports team via Facebook is annoying (especially if your team is eliminated by that point), it is nothing compared to when your Facebook friends offer armchair sports analysis. You have to love those brilliant comments like, "Arian Foster is a downhill runner," or "Chris Paul is so clutch." Not only do these comments not actually mean anything, but if we wanted sports analysis, we would have gone to any of the dozens of websites that cater to fans, including ESPN, an outlet that offers so much integration into your life that we fully believe they will someday offer to implant chips in our heads that update us on our fantasy football teams.
Also ... Go Steelers.
