FTSU

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.
