Needlessly complicated Chinese words

I was just talking to a friend about needlessly complicated Chinese words. Check this word out

龘 dá

Three dragons. It means "the impression of a flying form that looks like a dragon"

齉 náng

It means "to snuffle".

The ultimate needlessly complicated Chinese word, I think, is biáng. I can't even find the chinese character for it, only an image

I dare anybody to try to write these words
