Words you can keep
An individual who talks about their significant other to friends as if they do not care, but when their better half is around, they are completely invested and bending over backwards for their partner.
Typically, a male talking shit about his girlfriend: "She is such a whore! I'm only with her because she is a great lay." Then his friends discover a letter, email or facebook message which displays his softer/in love side. In such a case, friends will call their friend a SEMP anytime he talks more shit or leaves to hang out with girlfriend.

sic semper tyrannis

Latin, translation: "Thus always to tyrants", purportedly (but unlikely) uttered by Brutus at the assassination of Julius Caesar. The phrase is meant to signify that tyrants will always be overthrown and removed from power.

Sic semper tyrannis.
