According to Wikipedia: Snowflake as a slang term involves the derogatory usage of the word snowflake to refer to a person. Its meaning may include a person perceived by others to have an inflated sense of uniqueness or an unwarranted sense of entitlement, or to be over-emotional, easily offended, and unable to deal with opposing opinions.

I looked it up out of curiousity. Yes, it’s a bullying term.

Bottom line; you have to make your friend respect your boundaries. If he keeps doing what you asked him not to do, he’s provoking fights with you. You’ll have to distance yourself from him to enforce your boundary, then you lost the friend. But he wasn’t a good friend anyway.

It hurts to lose friends and family, but in time you’ll find better friends who respect you.
