What does "FB" stand for in text message lingo?

In text message lingo, "FB" stands for Facebook. Social media abbreviations on Twitter include "FF" for Follow Friday and "MM" for Music Monday. Twitter also uses "DM" to indicate a direct message.

Social media and text messages use many of the same abbreviations. The letters "HTH" indicate that the sender offers assistance and good wishes. The term "ROFL" translates to "rolling on the floor, laughing," a reaction to an extremely funny joke or situation. Senders use "NSFW" to inform the receiver that an attached link is not appropriate for the workplace. The abbreviations "FTF" or "F2F" signify an interest to meet face-to-face rather than in a virtual setting.
