(I finally learned what “wb” means, and then they throw this at me.)
AFAIK.
According to the wonders of Google, it stands for, “as far as I know”. –as in, “Mushmom respawns about forty-five to sixty minutes after she’s killed, AFAIK,” or, “afaik, all the sanctuary entrance maps have cold eyes.” It’s mostly used as a disclaimer. People who are not sure about their statements’ factuality use “AFAIK” to tag them, even when they have sufficient time to type out an entire sentence. I’m not saying that all abbreviations are bad. Even I use certain abbreviations which help express my anger.
