I've been waiting over 5 years with bated breath for someone to say that! Finally I can breath again!
Now that we've cleared that, we return to the Gemorah:
גופא
אמר ר׳ שלאנקס משמיה דר׳ דאן:
A forum isn't a chat session. Please use full words and regular english.
Using expressions in other languages seemingly doesn't violate that rule. The rule is to exclude Millenial style writing which is commonly used in chat applications, almost never uses capitals, uses characters to represent syllables (u for you, y for why, b4 for before, etc.) and drops certain elements out of sentences (if they can be called such).
