Name of the anti-pattern of keeping old obsolete code around

Recently I took a look at some code I'd committed to our version control system at work, and I found a bunch of it had been replaced (that's OK) but the old version was still there, commented out.

I guess the guy felt a bit "insecure" about deleting it, and therefore left it there commented out. However, that's not necessary, as we are using version control. (The old version was wrong, so it's not like it's going to be needed in the future.)

These stackoverflow questions deal with the question of if leaving old code like that around is a good idea or not:

• https://stackoverflow.com/questions/123423/do-you-leave-historical-code-commented-out-in-classes-that-you-update
• Old Code in comments

However, my question is: is there a term for this sort of thing, or an "anti-pattern name" i can quote when talking to my colleagues about it?
