Define T Minus Meaning

The phrase is an exclamation marking the event that the user needs to take a massive dump, often one that is minutes or even less to where shit hits the fan, quite aptly.

It's your standard garden variety "lesbian gay bi transgender" but minus the transgender.

A small but savvy minority of LGB people recognize that LGB causes are not the same as transgender causes. The former has to do with sexual orientation, the latter has to go with gender identity regardless of sexual orientation. People who support this view do not think that transgendered people should have no rights, but simply that they have nothing to do with LGB rights, and therefore oppose the use of the term LGBT and the countless other variants with all sorts of different letter combinations on the end.

The most outspoken proponent of this view is John Aravosis. He has pointed out that LGB activists have been trying to pass the Employment Non-Discrimination Act (ENDA) for 30+ years, and just when it actually had a chance of finally passing in 2007, they tacked on the T to make LGBT, and then it had no chance of passing. Thus, the initialism LGBT (and any other unnecessarily long variant) has actually held back LGB rights.
