"Last year's Thanksgiving was an utter nightmare! Somebody should really tell cousin Shayla to take a hiatus on the wanton procreation. We needed three turkeys to feed the sudden kinflock."
Are you suffering from the sudden explosion of nieces and nephews? Are you tired of all the precocious Braydens, Jaydens, Emmas, and Madisons in your extended family? Does your cousin Shayla randomly browse a high school yearbook and manages to sleep with every guy on the page?
Then "kinflock" is the word for you.
