A Gibbo
A spineless sissy who hides secrets like a coward, and if you ask him about them, he'll run away like he's being chased by a gang of fags.
''He's a gibbo. He's got secrets and he's too scared to tell anyone.'''
''Gibbo ran out of the room when I asked him about his ex.'''
''He's a gibbo. He hides secrets like they're going to kill him.'''
