Throw like a girl is an insult when directed to a man. It is not when directed to a girl., unless she is a Women’s Softball League pitcher, then she still throws like a girl but a lot harder.
In other words, “....like a girl” is an insult, no matter what.
You all know it is true.
Don’t hand me that obfuscation of “when it’s a man”.
When was the last time you heard someone COMPLAIN “you.....like a boy” to a girl?
That’s right. Never.
