achin' 'n' begs
Refers to the agonized feelings/actions --- i.e., extremes of "pain and pleading" that may include severe stomach-cramping, extended bouts of tearful wailing/imploring for more-filling menu-choices, etc. --- of a "pork 'n' poultry" lover who is unexpectedly being forced to "go vegetarian" or otherwise follow a much "leaner and blander" diet than the rich-flavored grease-and-carbs-laden feasts that he'd been accustomed to chowing down.
(from author Steven Kellogg's "modernized" version of the classic children's tale "Chicken Little"): After being convicted of assorted heinous carnivorous crimes, bacon-'n'-eggs-loving Foxy Loxy was totally in the throes of tortured "achin' 'n' begs" when he learned that his diet in prison would consist of green-bean gruel and weed-juice.
