A Goon in the singular is an idiot that does idiotic things with no real harmful side effects other than to them selves. Mostly, the outcome of their goonish behaviour is relatively
entertaining to the rest of the world.
The plural, Goonie, is totally opposite. You can only be a Goonie if you have 4-5 other Goons with you. To be a Goonie should be everyones goal in life and if ever reached will
automatically rocket you to the top of the food chain, the height of coolness and triple your chances of
getting laid. There is a warning in the small print however, Goonies never say die, so if you aim to be a Goonie, SAS training is advised.
