The first use of the term "rough and tumble" for fighting dates back to the early 1700s in the North American frontier. Rough
and tumble fighting was the original American no holds barred
underground hybrid "sport" that had but one rule - you win by knocking
the man out or making him say "enough." All techniques of boxing and
wrestling were allowed, and competitors thought nothing of biting,
eye-gouging and reaching into an opponent's clothes to attack their
genitals. People were maimed in these brutal fights, which were often
referred to in historical records as "boxing matches." 
The
origins of the term "rough and tumble" was from "bragging and fighting"
introduced to the North American back-country from England where it
came to be called "rough and tumble." In North America, as in 
Sporadic attempts were made to suppress "rough and tumble." But
in the southern highlands, rough and tumble retained its popularity.
During the War of Independence, and English prisoner named Thomas
Anburey witnessed several backcountry gouging contests. "An English
boxing match," he wrote, ". . . is humanity itself compared with the
Virginian mode of fighting," with its "biting, gouging and (if I may so
term it) Abelarding each other." Anburey described "a fellow, reckoned
a great adept in gouging, who constantly kept the nails of both his
thumbs and second fingers very long and pointed; nay, to prevent their
breaking or splitting . . . he hardened them every evening in a
candle." Blood sports have existed in many cultures, but this was one
of the few that made an entertainment of blinding, maiming, and
castration." Later when the Lancashire wrestling style made it to the
US and was blended with the "rough and tumble" mentality, and the
gambling involved, the very aggressive American catch-as-catch-can
style of wrestling emerged and created some of the most outstanding
grapplers in the word. Much of today’s MMA fighting concepts can be
traced to these early "shooters."
