Twenty Minutes Of Oxygen Left Edit Meaning

1.

an obscure euphemism for, like, a really fucking critical moment. as in, if someone says "you'll know when" well when you have twenty minutes of oxygen left is prolly a pretty good indication of "when."

"yeah, so when i only had twenty minutes of oxygen left I figured it was pretty clutch and remembered when my future self said "youll know when" and figured it was pretty much when, so i wnt for it."

See mission critical, time travel, sitch
