   We've got pinecones up the ass this season since it was so wet last spring.

The word ass can change, especially in literal senses, to a euphemism such as seat or to another word understood in context to be a synonym, even when such words on their own would not be understood as synonyms for ass. Thus one hears up the seat and up the pipe but rarely even in mixed company does one use phrases such as  you bet your pipe.
