blood, hacking female hygiene stuff to serve my (non-female) needs
@uniporn something like this still exists in its original purpose in the US army but also if i'm remembering right usually contains a powder that acts as a styptic to immediately help arrest bleeding, but also hurts like fuck and is thus really only used in "OK SOLDIER IT'S EITHER THIS OR BLEEDING OUT GOOD LUCK" type situations!
