The act of heading out for a drink on a Friday night after work with friends. (FRIday driNKING). Frinks (the drinks) and Frinkers (those that head out Frinking) all stem from the root verb "To Frink". Originated amongst ex-pats in Buenos Aires in 2010 and has spread to other English language countries as travelers have passed on.
I'm heading out Frinking tonight.
Every week since 2010, Frinking has taken place in Buenos Aires on a Friday night, with a Facebook Events Group, and Meet Up Group to promote it.
