Commonly read as "tee zero." Internet slang, used primarily by the programming/cracking/hacking crowd – though its use among gamers has become more widespread lately.

Meanings:
1). the beginning
2). since the beginning
3). at the beginning
4). preemptively

Synonyms: all along, from the start, preemptively, beforehand

Origins:

Contrary to the belief of some, the etymology of t0 is probably unrelated to NASA's MET system (see tminus). Rather, it more likely has origins in the statement t = 0, in this case representing the time at which a particular event began.
I knew t0, but didn't tell anyone.
I created a rudimentary map of the area t0 to avoid any potential issues later on.
Looks like they had the game in the bag t0 – we lost before it even began.

Read as Trump’s naught or reproduction number. The total number of people Donald J. Trump had infected and is likely to infect in coming days and weeks, because he selfishly and vaingloriously refuses to protect others by wearing a face mask and to isolate himself, when he is still not corona-free and is contagious to others.
Based on media reports, the White House superspreader’s T₀ among his entourage has so far been no fewer than a dozen victims.

Back when I lived in upstate new york 

A meaningless, unimpressive, self-serving introduction. An indicator that the story about to be shared will be pointless and dumb.
Back when I lived in upstate new york, I also had to park on the street - on two occasions, we got enough snow, mixed with just the right plowing, that my car was lifted off the ground from so much snow being jammed underneath it.

Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.

Me: Woah! TLDU!
