When Josh says JB's eyes are all moony, it signifies that JB's expression is dreamy, romantic, or distracted, as if lost in thoughts, particularly those inspired by love or affection. This expression often implies a sort of wistful longing or fanciful daydreaming, and it may convey a connection to the glowing, romantic imagery often associated with moonlight in literature and poetry.
The term could also imply JB is displaying an air of quiet contemplation or reflective tranquility, inspired by the night atmosphere in the presence of the moon. The use of moonlight in literature is a prevalent motif to symbolize such emotional states, as moonlight often casts a serene, soft, and mysterious glow that can affect the mood and perception of characters.
