Little Boy Hands (LBH) Syndrome 

When a grown man has the hands of a middle school aged year old boy. Everything else is very manly except for the hands. They are, however, known to be rather adorable. Some characteristics include: hairlessness, excessive nose picking, soft texture, perfect cuticles, shiny nail beds, short fingers in comparison to arm length.
