Examples of use of up the duff
1. "Hey, bet she‘s up the duff," he observed to anyone listening.
2. I read the Mail today, oh boy, It said he stabbed her with a broken glass, Grabbed the respondent by the neck, Though she was up the duff, He’d always treat her rough.
3. As an extra precaution, I believe it is wise not only to stand up directly afterwards, but also to perform some vigorous knee jumps, or jacks, possibly from the top of a wardrobe, which not only stops you having a baby but also nicely puts the kybosh on any chance of a further date, as you are obviously a loon and wholly unfit to be a mother, even though there is every chance you are well up the duff already. . . . . . . . . .
