for a 12 year old boy?

Recall that in Game of Thrones the young Arya (she/her) grabs a light fencing stabbing weapon with two hands and flails it about like a 12 year boy playing with a pretend broadsword.

Syrio, her teacher, proceeds to correct her and teaching the beginning fundamentals of swordplay.

The GP has used a simile cussing like a 12 year boy and could perhaps instead used braying like a donkey, bellowing like a sea lion, cursing like a sailor, etc.

The use of a simile does not imply that the subject of the simile is a 12 year old boy, a donkey, a sea lion, a sailor, etc.

It doesn’t seem like your parent comment is referring to the “12-year-old boy” part of its parent comment, but the “(…) information he might have (…)” part (near the end).
