tumblr is a social media website best known for getting offended by everything. As it gets offended by everything, it is a great source of memes, but not as good as MS Paint and GoAnimate. It is also very triggering, so view it with caution. It's biggest contribution to society was the idea that anyone can make up a gender so they can be special or "oppressed" while still being a "cis" white "female". Da Quintet use it to look at horrible deviantart drawings, instead of just going to deviantart. Sharpy likes it because now he has a vajoiner and tits, and also likes their UwU face. Of course, the most important thing you need to know about tumblr is that everyone on there wants to fuck the Once-ler from the Lorax movie.
