A person who seeks a homoerotic friendship with a already documented and established ('made') Jock-Sniffer of an amateur athlete, coach, or parent of the athlete. Jock Sniffer-Sniffers routinely frequent college football message boards seeking their targets
Mark wants to be a jock sniffer, but he does not have the comnnections to the athletes or the coaches. So he hangs out with established or 'made' Jock Sniffers, Larry and Burl, who claim to know athletes and/or coaches. Mark's worship of Larry and Burl creates the Jock Sniffer-Sniffer relationship.
