Soy boy means: An effeminate or unmasculine man.. It is internet-era slang, commonly seen on TikTok, Discord, Reddit or X.

“If we could only change the narrative around AI to be that if you use it, you're a low value, beta cuck soy boy. That would end AI in a heartbeat.”

For ESL learners
soy boy means: An effeminate or unmasculine man.. Register: very informal, internet slang. Suitable only for casual conversation, chat and social media. Do not use in business, academic or news writing. Common learner mistake is using the word in a register it does not fit, or assuming a single global meaning; always check the context before producing it yourself. A formal-English equivalent (a synonym or descriptive phrase) is usually safer in writing. When in doubt, paraphrase rather than reuse the slang form.

For specific readers
Why is this section here?
Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.
