What does stock mean?

I like to make all my crafts without tinker panel or mods, so I guess I am a stock person.

Thank you @SupremeDorian @WNP78 @Kell for the explanations.

@Kell I wouldn't say tinkering is dishonorable. It is genuinely useful at times. For example, one could use it to make a large Heat Shield out of an empty fuselage. It has useful properties, but can easily be abused.

Different people have different ideas of what it can mean. It could mean that it can run on a stock version of the game without needing to download mods, it could mean that it was made without overload/xml modding, or it could mean that it wasn't made using the tinker panel. Depends how much of a raving lunatic said it.

An honorable way to produce a usable craft

No tinkering or XML modifications
