I have seen an old and very rarely used character that consisted of four traditional dragons (龍). As I remember it meant "talkative."
That makes a total of 64 strokes, are there any other characters with more strokes?
1. biang
Well, the first one that came to my mind is biang, as in "biang biang mian" - which a quick Wikipedia search shows has 58 strokes. This is still in some use (and I've seen it in restaurants), if that means anything to you. It is not, however, found in dictionaries.
2. zhe
Sadly however, biang doesn't have the most strokes (although I would argue it's the most complex) - Wikipedia has a page on complex characters as well, and according to them zhe, meaning verbosity, was the most complex/has the most stroke orders - possibly the character you are referring to, as it is just long (龍) times four:
3. zheng
It also mentions zheng, another 64-strokes character meaning flourish, as being equally as complex:
The page on Wikipedia goes in to a lot more detail, so I suggest you check it out.
