gobshite

What it means

1. 1.

   A fool, specifically a loud one who talks confident nonsense. Stronger than eejit and genuinely rude, though common in ordinary adult speech and heard on national radio.

In use

• Don't mind him, he's a gobshite.

• I made a right gobshite of myself.

Where it comes from

'Gob' (mouth) plus 'shite'. Gob comes from Irish 'gob', a beak or snout, and is the reason the insult targets talk specifically rather than general stupidity.
