Internet acronym for 'good night', based on spelling out the '8'.
All right, g2g, gn8 folks!

despite the other definitions, the 8 in gn8 has nothing to do with any american word. gn8 is short for Gute Nacht (goodnight in german) Acht is 8 in german, which also rhymes with the german word Nacht, meaning night
