A jock-a-rambo is an athlete engaged in violent contact sports who is highly aggressive, often in part owing to the use of steroids. More than other athletes, his violence defines him. He suffers from the mindset that the hard hit, high sticking, whip tackling, spearing, brushback pitches, hard sliding, and other marginal or illegal techniques are essential ways to gain an edge in competition.
Jack Tatum, free safety for the Oakland Raiders in the 1970s, paralyzed Darryl Stingley of the New England Patriots in a 1978 NFL preseason game with a very violent, though legal, hit. He recounted this incident in the ultimate jock-a-rambo book, THEY CALL ME ASSASSIN, published in 1979.
