Many carbohydrate-containing foods cause gas and bloating (vs. fats and proteins, which produce very little gas). Starch containing foods such as corn, noodles, pasta, potatoes, and wheat, also produce gas.
SJWs are people for whom activism is an activity, like shopping, or being on a sports team. They bond with one another over having the right opinions. Cheap and easy, with no chance of criticism from others, social activism provides a hobby to talk about at the local bar after a long day of work.
I think that term, somehow, works both ironically and unironically. Ironically, it's a term used to describe far-left-wing armchair activists. Unironically, it's a term used by said activists to describe themselves, because that's how they perceive themselves. I'd like to elaborate on the term, shit lord. It is not really a word sjw use anymore, its mainly used in parody and satire.
