How to disable the trash can in KDE

From what I gather, the idea of a "trash can" is of Windows descent, and was to make a user's life easier. However, when I go to delete a file, *I don't hit delete unless I know I don't need it and will never need it ever again. Period.* I'm currently running OpenSuse and the trash can is a confusing "feature" (as I can't seem to find WHERE it is) that sometimes even creates cute little directories on my flash drives for trash. Basically put, I don't like the trash can idea. Is there a way I can "turn it off"? I'm assuming it's a filesystem thing, so it might be harder to do then I predict. Basically, I would like to perform a rm -rf on the file that is selected (-r in case it is a directory). Is this at all possible?
