A Hodad is an older surfer, who most often rides a longboard and is able to get onto waves before the shortboards, but because the hodad is riding a longboard, he is unable to shred the vave the way a shortboarder would be able to do. The opposite of a gremmie, a younger surfer that rides a short board but who drops in on you everytime.
Someone who is very uncool from the perspective of a surfer of skater. Mainly due to the fact that they are not a part of their community and thus have no board (skate/surf).
