The secondary definition, as listed in the NerdSpeak Dictionary, is "Bring It On, You A** Clown"
I think I like that one better. It's funnier and the tacking on of "cowboy" on the first one is unnecessary and makes it bulky.
I'll go with B as the preferred meaning. But I think Strac meant the first meaning based on the context.
Thank you for this additional information.
