Seppuku, Hara-kiri, Banzai, Kamikaze, "Fucked your mother/sister/daughter/granddaughter/grandmother" (maybe all of them at once, and in the modern world, both genders can do this - an act likely to get you killed by their relatives, so thus akin to suicidal conduct). Snacked on hemlock. Croaked. Passed (literally true if you CTB in a field where destructive feral hogs roam, although if you hate those creatures, you can also kill them in turn if strychnine poisoning is your CTB method).
Wait, wait, wait...are you actually suggesting that opponents of Sanctioned Suicide have a brain? (I've read and seen some of their rhetoric against us, and in their YouTube clips, I could swear that when I look in their eyes I then see the backs of their heads!)
Of course! HAPPY ENDING! (Wait... did I just read that post wrong...or not?)
