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.

Eye detector - when someone with a lazy eye lies, their eye tends to start rolling into the back of their head.
Someone with an Eye detector might be sayin something like, "Dude, i got my lazy eye when i got jumped by a gang of mexicans in Grand River", and while he's saying it, if his eye starts to slowly disappear - He's lying!

Detector vans where first introduced to the UK in 1952 by the BBC.The reason for these vans was to detect who is watching live broadcasting without a TV Licence.What the BBC didn't tell the population was that this was a load of pish.

In the 55 years that they have been prowling the streets of the UK,they have never taken anyone to court on the strenth of this detection equipment.
