The act of forcing your index finder up the clothed anus of a friend or
stranger, so that they cry out like a
startled goose,
the word "goose" must be said before the action takes place
i shouted goose in the pub, no one
covered up, so guy in front of me got a bit of a surprise when my finger
penetrated his anus through his pants, so shocked infact he had
no words to protest against the action, so he just squawked like a dishevelled goose.
