Mouth
of Irish origin.
Word in the Irish language.
In Irish (Gaeilge)gob, meaning beak

Stands for Good one Benny. GOB is a friend that says something wildly unfunny while convinced it is actually funny.

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

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.

It means spit....

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.
