Jul 15 Word of the Day
The safeguarding of Earth and other worlds from biological cross-contamination (i.e. billionaires with too much time on their hands).

Also known as “planetary protection.” Planetary protection / quarantine “reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.”

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.
Billionaires are having a dick swinging space race while the earth experiences record breaking heatwaves that cause sea creatures to literally cook inside their shells. We need planetary quarantine.

A typical Australian male teenager aged between 18 - 35 years old.

A 'Maddog' is a male who loves "gettin' on the piss" (consuming a lot of Alcohol, typically Hahn Super Dry or West End Draught) - once intoxicated a 'Maddog' generally is unable to control his actions, physically and verbally.

'Maddog's' have a large circle of mates (friends) also, who together they consume alcohol in ample quantities.

Generally a 'Maddog' speaks his mind, curses, likes to throw his weight around and have a good time, without considering the implications of his actions.

'Maddog's' also attend most Australian Music Festivals.

They also love going to Bali and Thailand for a holiday.

Most 'Maddog's' are very confident beings, and they like to participate in active sports (AFL, Soccer, Gym etc)

Most 'Maddog's' also do alright with the ladies (unless they get too drunk and hurl verbal abuse towards the female gender, becoming an increasing issue).

Most 'Maddog's' have lost their driver's licence at some stage of their lives (Drink driving, speeding, burnouts - burnouts are usually performed to impress other fellow 'maddogs')

Slang term for Mogen David wine, especially the fortified-wine MD 20/20 variety. The MD stands for Mogen David. It was shortened to MD for their line of bum wines to differentiate between their more respectable (if no less nasty) line of kosher wines.

Contrary to popular myth, there has never been a wine sold under the name Mad Dog.
Got me some Mad Dog last night and got fucked up.

There's a new flavor of Mad Dog called Buck Bunny and it's licorice! Nasty!
