Fat jokes have taken a step on the dark side. Where they were once limited to harmless banter, adults are increasingly making more (and meaner) "fat shaming" comments on the Internet.

Many Facebook users remember Maria Kang, a mother of three who posted a photo of herself in workout attire along with her three young children with a caption that read, "What's your excuse?" The photo was received as controversial, as many viewed it as critical and fat shaming against women's bodies. One Facebook user commented on the photo writing, "I think this picture and the presentation along with the caption was off putting and upsetting.  There are thousands of other ways to show off a fit body without wearing a bra and underwear for the nation to see. Secondly, "excuses" come in every shape and size. I think for most women it's about priorities, not excuses!"

More recently, comedian Jay Mohr came under fire for disparaging fat shaming comments he made about actress Alyssa Milano. Mohr mentioned that when he saw her at a public event "It seems like she had had a baby and said, 'I don't really give a s--t' ... I read it on her gut." Milano took to her Twitter account in response, tweeting "So sorry you felt the need to publicly fat-shame me. Be well and God Bless. Please send my love to your beautiful wife."

Fat shaming comments have even been thrown around about highly acclaimed actresses. In a scathing review published in The New York Observer, film critic Rex Reed called Oscar-nominated actress Melissa McCarthy "tractor-sized", going to call her out as being obese and obnoxious.

With so many accounts of fat shaming on the rise, who do we point the finger at? The Internet? The media? Hollywood? It seems no one has the answer, but for now it remains one big, fat question to ponder.
