That's just absurdly PC.
Maybe dreamed up by the Campus Support-Group For Man-Hating Lesbians.
Generally I'd say it just expresses a guy wants to have sex with a girl, and uses a trendy slang catch-phrase to express that thought. It could be argued it's crude and not respectful of women, but hardly an inherent expression of violent intent.
Any more than when someone says "hit it" to a band onstage.
