The Suicide Programming Language
The suicide programming language is an esoteric programming language focused around birth, having kids, murdering your family, then killing yourself. There's a caveat tho: all of your children must do exactly as you did, with the only data being set to them is what is left on the stack. And, your children run concurrently at the same time as you, and you aren't guarunteed when exactly they will do things.
See the example code for examples in the language.
