A hypothetical,
mental device that represents a person's ability to detect deception, dishonesty, corruption, fraud, insincerity,
hypocrisy and falsity in others. A person with a "built-in bullshit detector" usually knows when someone else is lying, or putting on a false
front for appearances. These people are not easily conned, coerced, lied to, tricked or manipulated because their "bullshit detector" allows them to avoid falling prey to such things. These people are also often slightly
cynical, extremely perceptive, intuitive, shrewd and just generally highly intelligent.
Disagreeing with someone or something doesn't mean you have a "bullshit detector". A lot of people think they possess a "bullshit detector", because they
dislike or complain about a lot of things, or enjoy sharing their, often
unpopular, opinions (in all caps) online. In
reality, these people just have opinions, they are not actually good at detecting deception. In fact, they are probably more likely to be victims of the very same bullshit that someone who actually has a bullshit detector, is trying to make them aware of, but due to their reactionary natures, obtuseness, and lack of bullshit-detecting capabilities, they are either unwilling or incapable of accepting that they've been bullshitted on.
Example 1: Nellie's new boyfriend tried very
hard to make
us all think he was a good
guy, but I wasn't at all surprised when he turned out to be an abusive
asshole, because my bullshit detector went off the moment I met him.
Example 2: If all Americans possessed built-in bullshit detectors, half of them wouldn't have elected a sociopathic , pathological
liar and conman in
2016.
Example 3: If I'd had a bullshit detector, I wouldn't have fallen in love with a narcissist who ended up swindling me for every penny I had. She even stole my Starbursts!
Example 4: "I stopped hanging out on Facebook when all the gossip, drama, backstabbing, fake news, fake
bitches saying fake shit, ass-kissing, bullying and pandering for popularity, caused my bullshit detector to overheat and then it exploded. So now I have no way of avoiding all that bullshit and it's just not worth it.
Dialogue Example:
Jenna: Hi Lydia! Wanna hang out with me and my girl-
squad?
Lydia: Naw, my bullshit-detector is telling me you're a garbage person and I would regret it.
