to make a phenomenal catch , as Randy Moss would do. The catch has to be bonerific. In a situation like this, the defender is always rihannaed. On the way to the end zone the reciever has the option to be a swagger jacker and embarrass anybody else he pleases.
Jeff: Hey , Roy , did you see that catch ?

Roy: Fuck yeah man , Jared is really Mossin' on em today.
