An online blog site where fatty's, hamplanets and mini moons gather to make themselves feel better. Usually associated with fat acceptance, thin privilege and cake retention instead of water retention. Also related are the terms, healthy at any weight but not to exclude, a scale is just a number.
Chestbrah: Did you see the new fat acceptance blog on Tumblr.
Zyzz: Nah brah, don't have time for that.
Chestbrah: Understand, let's hit the gym and check our privilege.

Zyzz, Chestbrah:LOL....HAHAHAHAHAHA
Zyzz: Let's get a double scoop of D-Bol

A place where you can express yourself, where no one will judge you. You can reblog anything you want. You can tell your followers anything. Its basically a place to vent, and for whoever will listen. It's very time consuming, because it's more than amazing. You'll find yourself on it more than talking to people. and hanging out with friends. It's a place to be free.
Tumblr person: I love tumblr. It's the only place I can be myself.
Other tumblr person: I know. I wanna keep mine forever.

A secret place.
Chris: Hey lets go on Tumblr tonight.
Zooey: Forever alone.
A toxic cesspool of a website where people claim that you're allowed to speak freely, but is filled with a great deal of intolerant morons who take any chance they have to snap at you and send death threats via anonymous ask. Generally divided into the 'hipster' and 'fandom' halves that are supposedly at war. Lots of social justice 'warriors' that will spew hatred even for people who are innocently ignorant of issues and tell them to educate themselves without helping them (and being right by 'default' since you're evil to argue with them), people who fetishize homosexual relationships and force it onto every male character they see while claiming they're pro-gay rights, demonize female characters while preaching feminism, obsess sickeningly over the UK/England/Great Britain (or mostly just the stars of Sherlock), and threaten to kill anyone who gets in the way of their otps or doesn't share their "Feels" about them. (Such as celebrities' significant others).

Hell on the internet.
Average tumblr blogger: "Tumblr is the best website EVAR!11!!!! But stay out if you're from facebook no one needs you people here CHECK YOUR PRIVILEGE CIS SCUM!"
