One who roams between many groups of people, partially as a result of shunning, partially from personal drive to move up the social hierarchy. Groups tolerate a friend nomad on the basis that they know he will only hang out with them once in a while.
Dude that Raffi kid is such a friend nomad. Two weeks ago he hung out with those freshmen, last week it was the football group, now he wants to hang out with us.... WTF.
