I agree with you on the use of the word "trigger".  I do, however, think that we should be careful not to dismiss things that put you in a certain state of mind just because some people have terrible experiences that are true triggers.    For instance, we all know that certain smells can easily bring you back years in time and make you very nostalgic.  It would be silly to call that a trigger in the same sense as a true PTSD sufferer, but that doesn't change the fact that it did "trigger" something in you. So I'm not sure what term to use but hopefully you know what my question was intended to ask.  And yeah, fatties using the word trigger as a catch-all for feeling bad about being fat are just...evil.  There's no other way to describe someone that, due to pure gluttony, tries to latch on to sympathy that is reserved for survivors of war, rape, or other terrible situations.
