Wangdong

a slow and/or sluggish moving shopping cart; these are left by smart shoppers at your neighborhood grocery store because they are blessed with faulty wheels or their axles arent properly lubed; Wangdongs cause anger because when pushing a wangdong you must exert non-equal forces with your arms in order to push the cart along smoothly, thus making one arm tired while your wangdong skids along the floor of each isle.

Yolanda: Hey, look at that guys wangdong, its totally draggin.
Frodo: I once had a Wangdong like that, except i exchanged it before it sent me into a vortex of spiraling fury.
