How do I know if someone is gay or straight if his social networking profiles are contradictory on the subject?

Okay, so there is this soccer player at my college. On his Twitter profile, he described himself as a "homo" in one of his tweets. I found him on Facebook, and it says that he's interested in men, but posts and comments and photos on his Facebook and Tumblr profiles seem to indicate that he is straight. Could he be gay, straight, or bisexual? Should I approach him in real life, befriend him, and see if I can find out for sure?

The only way to be sure is to ask him in person as the trend of "Faceraping" has became PRETTY popular these days...
