to hook in wif a chik is to perform sexual activities with them, possibly even root em. people normally try to hook in wif chiks at parties and/or whilst pissed.

the castle is the best fucken movie ever made. watchin this movie means making the move from being a pre-aussie to a tru blu aussie bloke. this movie has sum of the best and funniest shit goin out in it and also sum of the stupidest shit goin out.
Dale kerrigan (from the castle): i gave this elephant to wayne coz he is in jail. elephants bring good luck, especially wen the trunks are up, and this trunk was up. (later in the movie) I thought about wayne tonight... i thought about his elephant. i wondered if the trunk was still up coz that brings good luck.
