Children, especially really annoying, hyper children who always seem to be getting into trouble and/or everyone's way.
Can't I ever get a good quiet meal at this restaurant? Every time I go here, there are always a few rug rats running around who don't look where they're going!

(noun) A toddler or a young child who is not yet old enough to walk so crawls using all four limbs instead. A newborn baby or children under one-year old are sometimes referred to as rug rats.
Tom and Angela's little rug rat is only ten months old and he'll be walking on his own any day now.

Extremely small yet resourceful rats who live in a rug. These diminutive rodents make their burrows in the dark spaces underneath furniture amongst the hairs of your rug or carpet. They live on crumbs and have a tendency to collect shiny objects such as coins or keys, although they have been known to also steal pens, sweets and important pieces of paper.
Those darned rugrats have collected a huge mound of junk under my sofa again, yet the exterminator refuses to do anything about it.
