Slower windsurfing, sailboarding, or board-sailing with longer boards in a displacement or buoyancy mode and modest winds, as opposed to faster--planing or hydrodynamic lift--mode, with shorter boards at greater wind speed.
Planing is faster and gives more maneuverability, but requires a different technique from the displacement mode (which is also referred to as slogging or schlogging).

Found in wikipedia, under surfing.

Girl1: But he was cute!
Girl2: Well that's your mistake.

n. A combination of the words 'slug' and 'dog', slog generally refers to one who is massively overweight and often breaks to recover energy. The etymology is as such because the slog is slow like a slug, and easily becomes "tired as a dog". Slogs often appear to have a mental or physical disability, regardless of whether or not they actually do. As such, a slog may be outcasted as overly-strange or unsociable.
