Not a single person here has mentioned where and why these acronyms started from and there reason in this world. They started when txt messaging started to grow popular but everyone had regular cell phone with numeric keypads using T9 entry. It was a total PITA to type in long words so people starting shortening things and replaces letter combinations with shorter words which phonetically worked (ie: Ill B L8).
I don't see the big deal - if you don't know an acronym google it - next time you will.
BTW - IMHO the thread has me ROFLMFAO! :fail:
Those acronyms were around decades before the concept of texting, or the texting devices. Those in particular were used on bulletin boards (BBS) and Usenet before a PC was even available to anyone other than hobbyists. Acronyms have been in use over a hundred years before that.
