Someone who associates with both "nerds" and "jocks" and displays many traits
common in both groups.
These people are usually able to maintain relationships with multiple conflicting social groups at the same
time with ease. Occasionally nocks
will favour one group or the other and become valued in the group by filling a role others could not with out becoming alienated. Alternatively nocks may forgo interaction with social groups all together to focus on more personal, isolated individual relationships.
"Nock" might also be used to describe someone who can mix with any nearly crowd, or fits in with many
tight cliques including, but not limited to jocks, nerds,
preps, artsy, etc. or who posseses many of the traits common in different groups.
"There are few examples of characters that are nocks in popular culture because most stories rely on pre-established archetypal assumptions, but I suppose
Michael Weston from the series Burn Notice could be considered a nock."
"In every sense,
even socially, he's a
jack-of-all-trades; he's a nock."
