Expression standing for "Show your tits or get the fuck of".
Normally used to express that what a woman said or wrote had no intellectual value. Can be used anytime in an attempt to diminish a woman's self esteem independently of what she does.
When a woman post a Youtube video, haters will for sure comment "tits or GTFO" indicating that it would had been better if she had shown her tits instead of posting whatever she had posted.
