This move requires the active participation of you, a camera, one unconscious individual, and a damned good friend. Pull your pants down to your ankles and position your ass hole about 6 inches away from the unconscious person’s face. Then give them a sharp smack in the face (they have to be sleeping on their back for this to work). When he wakes and raises his head in disorientation, your friend snaps a quick Polaroid of him tossing your salad. Definitely recommended when the victim has already spent time in prison as a prom queen

Captain Jack 

'Captain Jack' is the name given to a lad that 'harpoons' the 'Kracken' courageously and lives to tell the tale.

While they don't tend to remember the details in their toxicated state, others thoughtfully remind 'Captain Jack' of his adventures.

Usually quite often, in a banterous manner, dependent on the ferocity and ugliness/fatness of the Kracken. Being called Jack is also a factor.

Can be found at the same party as a 'chundersaurus rex'.

- 'Captain Jack! How're you feeling?'
- 'Whaaat?'
- 'Captain Jack? Y'know, you seriously harpooned the Kracken last night. So brave.'
- 'What are you on? I'm still hanging mate.'
- 'Ha, YOU BONED A FUGLY SLUT'
- 'Fuck.' (or other suitable expletive)

Handsome Jack 

Someone you can tell a mile off

Beautiful girlfriend/wife far far out of his league

Usually a monger

A propper half breed looking thing

Sometimes even makes a strong noise

And walks with a hunch and or limp

Mate did you see that gorgeous girl with a handsome Jack

How did that cretin get a girl like that
