Not necessarily a bad thing. A Gobshite, for better or worse, talks incessantly without provocation or purpose and most often without principle. The term Gobshite is Irish in origin, from the old Irish gob, or mouth, and shite, or shit. Shite of the Gob is the primary foundation of the word. It first appeared in print in the “manuscript glossary of US Navy terms” as a word for enlisted men, comparing them to tobacco spit. TheGobshite.com uses the word to capture a wide range of characters. In their first “Gobshite of the Month” they awarded Gary Busey with “Most Amusing” while also awarding Dr. Phil McGraw with “Most Annoying”. They also refer to their staff as Gobshites. Rightly so, a Gobshite for all their yammer can be quite entertaining, and therefore the term may be used as one of endearment.

Noun. Irish origin.
From the Irish "gob", meaning "beak" or "mouth", and the Irish "sial", meaning "soil".

"Gobsial" (which eventually became "gobshite") literally translates as "mouth of soil" and means a person who talks a lot of nonsense, a fool.
