look up any word, like timebomb:
 
1.
A shit that you spend a nice long time working on, but then when you're done, isn't in the toilet! You could have sworn you took that shit but it's gone! You wipe your arse and it's perfectly clean. Where did the shit go? I don't know!
Bob: Hey man! You didn't flush the toilet! Samwise: It's ok playa. It was a ghost shit... respek

2.
When you shit and whipe your ass and its clean. *then you look in the toilet, the shit went down the hole, thus simulating the effect that your shit never existed.

*the first condition is enough to constitute a ghost shit.
