I think 7 inches could be considered hung if it is also VERY thick-- like 6.5" around or more.
A 7 incher that is of average girth (around 5") would not be "hung" in my book. Big, above average...but not hung.
8x6 and up is hung to me.... and mine is nowhere NEAR that! I am only 6" x4.5". I just hang around LPSG to envy big ones!
