I don't use the term because I don't want to make someone feel shame about their body but I have always read uses of 'small dick energy' as insulting, not organ size, but the culture of toxic masculinity that believes the ridiculous idea that genital size is indicative of value.
And then overcompensates with other toxic masculine traits in order to PROVE stereotypical masculinity through other means. Depending on who is wielding it, it seemed a critique of toxic masculinity and traits and not actually buying into the idea that genital size = masculinity.
When it's used by feminists, I don't see it's focus on genitals as validating the toxic masculine belief that small genitals are indicative of less masculinity but a mockery of that belief system and its toxicity. I read it as mocking a kind of masculinity not a kind of body.
Because it can be read as body shaming or connecting genital size with bad behavior, I don't use it myself. I also don't use big dick energy. I don't use gendered or body-related insults. But I think the use of the term is far more nuanced than some are making it out.
@ahreaume I can’t figure how the term SDE could signify body shaming in the context in which it was used by Greta (is calling someone an egghead body shaming? I would hardly think so). Even taken out of context, the terms relation to actual body shaming seems tenuous at best and is more akin to a state of mind (self-insecurities; or the act of trying to appear overly masculine to compensate for a lack of masculinity).
