Yes, "sizeism" is a real world and, more importantly, a very real type of hate. The World English Dictionary defines sizeism as "discrimination on the basis of a person's size, esp. against people considered to be overweight."

As a kid in middle and high school, I was picked on mercilessly because I was overweight. And while I'm not a fan of Melissa McCarthy's work, I can empathize with her after she was publicly insulted because of her weight by movie critic Rex Reed.

Fox News reports that the movie critic is facing the wrath of people taking issue with his recent comments about McCarthy, who he called "tractor-sized" and a "female hippo."

According to the Hollywood Reporter, Reed, who writes film criticism for the New York Observer, shredded McCarthy four times in three paragraphs in a review of her latest comedy, "Identity Thief."

In addition to the "tractor" and "hippo" comments, Reed refers to McCarthy's career as a study in "being obese and obnoxious with equal success."

Paul Feig, who directed McCarthy in her Oscar-nominated role in "Bridesmaids," tweeted, "For his catty and school bully name-calling of the supremely talented Melissa McCarthy, I cordially invite Mr. Rex Reed to go f--- himself."

Though "Identify Thief" is doing poorly with critics, it's currently the top movie at the box office.
