Bullshit, but you can fact check it
We were arguing, and I won with some credible bullshit.
Not urban dictionary
Urban dictionary is not a credible source.
The credibility of a google search relies on whether or not it proves a party right or wrong in an argument
Schrödinger's Credibility:
"Google says that I am correct,"
"Well google isn't always right!"
or
"Google says you're right..."
"I told you!"
Credible and true are two different things, though it is often implied that credible and true are the same.
A movie is credible, there are are credits given to actors, directors, producers, sound and lighting crews, music, and anyone else involved in making the movie, and yet the movie is still 2 hours or so of unbelievable bullshit trying to pass itself off as believeable, (or feasible, as some would call it) which is really what people are doing when they call something credible. Saying something is credible encourages people not to keep questioning it, stopping just short of telling them they can't question it.
