吕小小布
[lǚ xiăo xiăo bù]
Possibly made up of someone's family name Lu (吕) and cute-sounding nickname 'xiaoxiaobu'. Xiaoxiaobu may mean small cloth (from Xiao meaning little and Bu related to fabrics), or just phonetically sounds adorable in Chinese culture. The whole username suggests someone whimsical and young-at-heart.
