the Nod consists of a up and down motion, this motion is shared mainly by minority groups, or those seeking to be included in a minority group. Since that group, which is smaller then the greater ethnicity is in need of "coolness" and acceptance saying a greeting such as "
hello" is not acceptable, instead the member of the group motions his head downwards, and the other upwards, to acknowledge their exsistance in the culture. Included in the 'nod' can also be a quick "
eh" or "hows it goin", anymore communication then that is unacceptable due to the lack of
relationship between the
two members.
