verb; to make a an error or mistake, particularly of a great magnitude. Attributed to the character Gob played by Will Arnett on TV's Arrested Development, who has a tendency to make such errors, followed by his catch-phrase, "I've made a huge mistake."

Mouth (Scottish).

A term inspired by the US comedy series Arrested Development. It refers to one of the show's central characters, 'GOB', an arrogant, shameless, self promoting showman.

In real world terms, "a GOB" is someone who displays the same classless showmanship, such as the lead singer of a pub covers band who thinks he's the greatest thing since Barry White but can't sing to save himself, or a standup commedian who obviously thinks his material is great, when in reality it stinks. Badly.

Mouth
of Irish origin.
Word in the Irish language.
In Irish (Gaeilge)gob, meaning beak
transfered as slang in English as mouth

A gob is a double dipped frozen banana with everything on it. It requires two sticks to support the extra chocolate and nuts.

To make a huge mistake and in realizing the err of your ways, say "I've made a huge mistake" in a very serious and theatrical way.

in the early years of u.k. punk to show appreciation for a band the audience would spit on them. this is called gobbing. i think it also carried over into hip-hop culture over seas but ice-t didn't like getting spit on very much so they were forced to kill the trend.
