What is Yeah Shit?
1.
The opposite of "no shit". Used to express acknowledgement of the not-so obvious.
note: Unlike its satanic opposite "no shit", this is not meant to be sarcastic in any way.
synonyms: "really?", "hmm, I didnt know that".
example 1:
Person 1: "I went to the dentist today"
Person 2: "Yeah shit"
2.
Opposite of no shit. Used when someone says something that wasn't obvious.
"My dog weighs 54 pounds"
"Yeah shit"
The person could have also said "really? i didn't know that" but this is where yeah shit comes into play.
