For someone born in the (nevermind :P), it's a new word for me. I grew up without hearing it. Back then, weight/size issues were always swept under the carpet, hidden until it was too late.
Insecurities about our body is dangerous and many good people have been lost too soon because of this.
Body shaming is real and drastic actions need to be done in order to address this issue properly.
A company that recognizes this is SM.
In their efforts to make every woman learn how to appreciate every inch of themselves, they have launched several campaigns and new lines for every age and body type.
