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')
