菊部扩张
[jú bù kuò zhāng]
This username 'Jubah Kuozhang' or 'Chrysanthemum Expansion' is a pun referencing 'anal dilation' as often seen in some comedic or absurd contexts. In Chinese Internet slang, the first character '菊' (ju) means chrysanthemum, which phonetically resembles another Chinese word '菊' (ju) used euphemistically in adult contexts. This type of humor is popular among certain communities online but may not be universally appreciated.
