Would you care to copy and paste at least the complete sentence, together with a description of the work from which it comes, and the approximate date of publication? I'd be glad to try to help, but not if I have to read hundreds of lines of text to find the phrase.
from Online Etymology Dict.root and toot: boisterous.
Root-Reduplicated form rootin' tootin' "noisy, rambunctious" is recorded from 1875.
www.word-detective.com/121603.html...the generally accepted theory explains "root," which first appeared in the sports fan sense in the late 1880s, as an extension of "root" as plants "take root," i.e., that the fans have bonded closely with, and "sunk their roots into" the team. A more vivid (and to me more plausible) explanation, however, has been suggested by etymologist Gerald Cohen, who points to the foot-stamping, clapping and shouting behavior of baseball fans described by 18th century sportswriters. According to Cohen, foot-stamping (or "pedal-music") was at that time a vital method of expressing support for one's team, and "rooting" originally referred to fans stamping their feet so hard that they might actually dig (or "root") holes in the ground.
