little bastards of joy
(n.) Children belonging to someone else that annoy you, Particularly neighbouring childer.
The little bastards of joy were setting fireworks off until two in the morning and throwing balls into my garden so I took them to thier milf and said I'd spank them hard unless I got something for my mental anguish. After putting them to bed, Victoria dropped my jeans and blew me, allowing me to deposit a sweet load of man milk into her mouth.
