TIL the Aztecs regarded childbirth as a form of battle. Women who died during childbirth were thought to rise to one of the highest heavens - the same one as for male warriors who died in battle.
Originally, 'based' was just a shortened form of 'based in facts and reality', but as it became prolific, the phrase's origin got forgotten, so now it's come full circle where people jokingly ask, "based? Based on what?" Completely ignorant of the original meaning.
Not in this context. The usage of "based" as a positive generic adjective comes from Lil B "the BasedGod" and has nothing to do with whatever you're saying.
