Sports figure(s) involved: Mike Vick
Year: 2005

Ladies, if you meet Michael Vick in a club and go back to his place for coitus, make him wear a condom. That seems like common sense life shit, but apparently not everyone is aware of the dangers of having unprotected sex with a 24-year-old athlete/dog-fighting enthusiast. In one such example, Vick was sued in 2005 for allegedly giving a woman herpes after a 2003 sexual encounter. During the trial, it was discovered that Vick used the alias "Ron Mexico" during STD testing and treatment, a revelation that caused the NFL to ban customized Falcons jerseys with "Mexico" across the back.
