Definition: The term 'supportability,' in the parlance of internet memes and everyday slang, refers to something that is perceived as reliable or trustworthy based on common usage. This can be a person's job performance, a product's quality, or even the reliability of your own beliefs.

Imagine someone has been known for consistently delivering excellent service at the gym, much like a reliable supportability. This type of supportability could manifest in numerous ways - from being punctual every time, to receiving prompt feedback on their exercise routine. Now imagine you're at an office party and all the people who work there are all in agreement about how great your boss is. However, when the conversation turns towards discussing your performance, you're faced with a sudden, unexpected change where no one can agree on what your performance was. In this scenario, you might say something like, "Supportability: Our boss doesn't really know who he/she is!" This will likely be interpreted as a joke and a dig at the idea that not all employees are trustworthy.
