Rafe87 is the worst type of Wikipedia editor. He/She is incredibly biased, and likes to use Wikipedia to try and trick people on the internet into believing in his/her largely unsubstantiated beliefs.
Rafe87's edits on Wikipedia are often unreliable, and intentionally don't show the whole picture of the subject matter at hand. Instead of trying to be as even and fair as possible, Rafe87 cherry picks pieces of evidence and presents them as emblematic of of the whole subject.
Rafe87 has very strong preconceived notions and will not let them be challenged by anyone. Rafe87 is not on Wikipedia to help people understand things better, he/she is on Wikipedia to alter public opinion to fit their narrative and beliefs. Unfortunately, this is often successful and many people on the internetwill let themselves be deceived by Rafe87.
Rafe87 is a dishonest idiot. Do not take what he/she says seriously.
While our lifespan is the number of years we will live, our healthspan is the number of healthy years we will have and our sexspan is is the number of years we will continue to be healthy enough to continue having an active sex life.
A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
