I realized then, I didn't know what an hollaback girl is, exactly.
I hypothesized, based on the profiles of women on myspace.com who were frequently importuned to "hollback at" various young men invariably clad in tank top t-shirts, and on the basis of this video, that to "hollaback" is to engage in casual sex; or at any rate to consent to same.
After explaining my hypothesis, and then proposing a reasonably sound study which could confirm or deny the hypothesis, the Hobbit insisted that my pondering was akin to "the geekiest dolphin in the seas, blathering about walking without actually having hind legs."
That aside.. what exactly IS, an "hollaback" girl? Shouldn't it more properly be an "hollabacking girl", since "to hollaback" appears to be a verb?
