I have often heard Orthodox Jewish kids use a phrase "t4". It usually means "just throwing this out there for attenton" but I am not exactly sure. I have finally seen this in-print in this Mishpacha article:
(My kids would call this a T4, like a flex that I got to chat with Rabbi YY, but if you know how accessible he makes himself to anyone and everyone — the harder the question and more perplexed the asker, the more eager he is — you know that this is a shvache [weak] T4.)
What is the exact meaning of this odd phrase, and where does it come from? (The closest I can think of is T9, the old cellphone text system, but that seems unrelated.)
