look up any word, like bae:
 
1.
(v/n) The act/sport of closely following someone while mimicking their gait, stride for stride, without being detected. More advanced ghost walkers can trail within inches of the target. It's also the latest fad in Europe that's actually NOT gay. Confucious say that to truly ghost walk, one most become another's shadow.
Bystander: Look! A pair of Siamese twins!

Jason: Nah man, that's just some dude ghost walking the other guy.
