buo·na·sé·ra/
interjection;
1) in Italian, «good evening».
2) In the Mandurian slang, expression of greeting that can be actually used in the daytime as a random
exclamation. It’s a synonym of the more famous «LOL» or «WTF», and it’s
particularly popular among teens of this area in South Italy, who enjoy screaming this shit out loud in a cringey way for no reason.
