a man's momentary regression back to a childish nature whereby he purposely goes out of his way to piss people the fuck off (ex. if hes having a bad day, then everyone else has to also)... like a little boy
person 1: "frank's been pissing everyone off all day just because hes in a shitty mood."
person 2: "oh, hes got the little boy syndrome."

When a little boy hits puberty and ejaculates for the first time. His expression is a little something like this: 0.o
Jesse: I think my son had little boy syndrome today!
James: Why is that Jesse?
Jesse: he looked a little something like this 0.o

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.
Despite being 6'7'', his little boy hands (LBH) syndrome make him look as if he wouldn't be able to hurt a fly.
