Anonomously rejecting a trade between opposing players in fantasy
football all the while
crying yourself to
sleep every night because your team is the worst thing to ever happen to the sport. This is basically a cock block in the world of fantasy sports and the two can be used interchangably.
"Someone pulled a Marshall and my trade didn't go through."
"Son of a bitch! Someone's team must
suck because my trades keep getting rejecting, who's the Marshall this
time."
"Did you see
Kyle pull that Marshall on Bshaw? He totally got cock blocked yo!"
