When somebody attempts to make the 'loser' sign 'L' with their thumb & forefinger held against their forehead, only they use their left hand instead of their right, thus forming more of a 'J' than a 'L'. Substituting the 'J' with the 'L' this person then becomes the 'joser'.
Johnny: "Hey everyone, look at Phil! He's such a loser!" (tries to make the 'L' loser sign using wrong hand)

Phil: "Johnny ... you're such a friggin joser man."
