Ah sorry.  Anyone who's been a Mailman admin knows that you get
notifications when messages are held for approval or when they are
auto-discarded.  Mailman includes the original message as an attachment
to the notification.  It's that attachment-in-a-notification that I'm
calling a wrapped spam.  An unwrapped spam might be the same original
message that makes it through to the list, or you get directly.  Wrapped
spams are very spammy but they are actually ham because of the
notification part.
