Well, this is a song about suicide, so I take it to be an abbreviation of Mach Selbstmord! (=Commit suicide!).
Trick 17 is just what you would call a supposedly very clever trick (ironically) - something that you just gotta know, but if you do then it's a piece of cake, really. Let's say a friend of yours is really desperate about something; you know how to help him/her out, and you do. Then you migh say, half triumphantly and half jokingly: "Trick 17!". It's like saying "Piece of cake, if you got the knack. Clever me!" Or he/she might say "Trick 17!", meaning "I see! Shoulda have come up with it myself."
