a coterie?

What would you call a group of men and teen boys, all dressed in camouflage with arms crossed, bodies leaned back, heads nodding, trucks aside emblazoned with numbers higher than 250, talking and talking...and talking (I also saw some wrestling moves being demonstrated)? A klatsch would connote coffee, possibly, and (caucus, cabal, clump, congregation and bloc, herd, gaggle, guild, ensemble) how about rabble? Coterie seems to be for people with similar interests, and these do, but it just sounds so durn feminine.
