In computer programming, code which flagrantly violates the principles of structured, procedural programming. Usually this means using lots of GOTO statements (or their equivalent in whatever language is being used) - hence the term, which suggests the tangled and arbitrary nature of the program flow.

Spaghetti code is almost impossible to debug and maintain, and rarely works well.

Programmers who write spaghetti code usually learned to code in an unstructured language such as BASIC, and never bothered to update their technical knowledge when they progressed to more serious languages.

The product of when some ignorant, over-confident fuckface writes in a hundred lines what you could write in a simple switch statement. This will undoubtedly include unneeded procedures and/or functions, unnecessary global variables, and unnecessarily abstracted include files. The purpose is to stroke the already inflated ego of said limp-dick programmer. And the result is that after management gets a clue and fires this jackass, you become the poor bastard who has to debug this pile of shit when it inevitably breaks down.

Security guard: What are you still doing here. It's seven o'clock. Shouldn't you be at home with your wife?

poor bastard: I'm still trying to figure out what the fuck Hank was trying to accomplish in this spaghetti code.

Horrible, horrible, horrible code, but still (usually) fulfills it's intended purpose. The English equivalent would be "I is go store buy vodka drink drunk sergawsdawq zzzzzz uuuugh talk loud". It is completely screwed up in almost every way, but you still know it meant "I am going to the store. I will buy vodka. I will drink. I will get drunk. I will babble incessantly. I will pass out on the couch. I will wake up, go to work, and complain about my hangover."

A coding style often executed by fucktards unaware of or to lazy to use proper structural coding styles. The term refers to how the code becomes a hard to untangle mass, mutch like spaghetti. The intent of code is clearer if functions, breaking, classes and loops are used, also you don't have to go through loads of lines searching about and there is a nice tree structure and bunnys start jumping about and doing a happy dance. There is no excuse, therefore, for coding such a messy way, because if people continue to do this there will be lots of people on fire(and not in a good way, see sexy lesbian orgy on fire).
