Acronym for "Fuck Their Shit Up", meaning, "Let's expose their lies". Now primarily used by the MRM (Men's Rights Movement) to bring about the reality of feminism to the world.

This is in response to the feminists' mantra "Shut The Fuck Up" (STFU, which is also a mainstream general purpose acronym), which they chant as soon as someone speaks up for the men's rights.
A: The feminist professor today said in the class that there's no sentencing disparity among the rapists based on their gender.

B: Look at this woman's case charged with 53 counts of rape and getting only 3 years with 8 year probation. Compare it to Jerry Sandusky's sentence who was charged with 48 counts. Make the masses aware. FTSU.
