For me, it was that the Internet never forgets and that you should never enter your real name. In my opinion, both of these rules are now completely ignored.
yah fr u tha fam
The only abbreviations in that are fr and u. Fam is slang for family, not a text only abbreviation. “Tha” is just a transcription of how someone may say “the”. Like “da bomb”. “Yah” is either a typo of “yeah” or the same as “tha”. This feels more like an insult against people transcribing vernacular literally. Are you racist?
