: : What's the origin of the phrase "so is a poster child for sth"?
: A poster child was originally a child with some illness or disability or other condition, such as being orphaned in a poor country, whose photo appeared on a poster soliciting donations to a charity that helped children with the condition. Later the term was taken up for humorous uses, like "That guy I went out with last night? He could be the poster boy for a remedial social-skills clinic." I don't know the other part, sth. sth or STH must stand for something that it's better not to have.
