“Quidquid Latine dictum sit altum videtur.”
“Anything said in Latin sounds profound.”

Technical jargon or acronyms convey esoteric knowledge or experiences, and can let someone subtly know you are part of their secret society, be it a military branch or RPI.

Sounding impressive means little when it is time to get stuff done. Tempus impetro stercore factum.
