Look at your hub. If it's got a smaller-diameter section toward the outside, then just go buy a lockring and remember that the lockring bit is reverse threaded. If it's a continuous diameter, go invest in some red Loctite, make sure you're running a brake, and possibly a BB lockring (more info on the above from someone with experience would be helpful) and start saving for a new rear wheel. Otherwise, stop riding your bike right now.
A suicide hub is a hub
without the ability to add a lockring as it only has one thread the diameter of a fixed/freewheel cog. Hence the possibility of a fixed cog spinning off if you skid, hence the name, suicide.
A track hub has, as you say, "a smaller-diameter section toward the outside". This is where the lockring threads to the hub. Not to run a lockring may be termed suicide by some, badass by others & stupid by the rest.
I'd say ride SS, with brake(s), or get a new hub.
