knock the back door in and put the extension up

Polite euphemism for anal sex, just crying out to be written into an updated Carry On film based around DIY enthusiasts.

Jack Douglas : "I'll be finished as soon as I've knocked her back door in and put me extension up"
Sid James : "Hwar har har!"

~Zen*Knack*Kiss~

~Zen*Knack*Kiss~, or Zen as she is affectionately known, is the most famous poster on Babycenter message boards. She is known to frequent the Bargain Hunting Tips For Parents board. Some love ~Zen*Knack*Kiss~, others hate her. Like Cindybin of Yahoo trolling fame, ~Zen*Knack*Kiss~ is not a troll in the traditional sense of the word - but her snippy comments and overinflated ego make her a well-known, infamous poster nonetheless.

Variations on Zen's screen name are zenknackkiss, her Yahoo ID; and zen_knack_kiss, not actually Zen herself... but she thinks Zen is so awesome, she set up a ~Zen*Knack*Kiss~ Worship Page on Myspace. You can find this Worship Page at http://www.myspace.com/zen_knack_kiss

~Zen*Knack*Kiss~ is God's gift to humanity.
