One who says things that are retarded on Tumblr. Usually in reference to the LGBTQ community. They are known for calling people misogynistic, racist, sexist, and other such discriminatory adjectives.
I went on Tumblr and said I'm new here. I said I'm a white Christian straight male, and i received hundreds of hate comments calling me a rapist, sexist, racist, misogynistic bigot. The commenters were all tumbletards.
