1.
Irish for "Little John" as in: "Little John Bull".

"John Bull" is a personification of England and Great Britain, like "Uncle Sam".

In Ireland, prior to Independence especially; to call someone a "seánín" is to say they think with an English perspective in mind and are British Sympathizers.

Essentially the Irish version of the term "house negro".
"Well, maybe if we just acted right the British would treat us better!"

"Quiet, you Feckless Seánín!"
