If a spammer or a virus sends out forged email (a "joe job") a certain proportion of it is likely to be rejected, e.g. because of incorrect recipient addresses or anti-virus or anti-spam or anti-forgery checks. If the rejection results in a bounce message the bounce will be sent to the apparent sender of the message, who is an innocent third party and the victim of the joe job. These bounces are backscatter from forged spam, aka collateral spam.
