Faceballs
The use of facebook to either 1)impress the opposite sex because in real life (face to face) the person would not have the guts, or balls, 2) using facebook as a forum to bash others when in real life (face to face) they would not have the guts or balls to do so.
Dave sure does have alot of female friends on his facebook, how come he never gets together with any? Dave has faceballs, he could never be as cool in person.

And
Does Dave have any idea who that guy is as he bashes his profile and pics? He would kick his ass if they met face to face. Oh yeah, he has faceballs. A real tough guy on Facebook.
