wrap rage 

Injuring oneself by using a sharp object to try to open hard-to-open plastic packaging like the kind they sell cheap consumer electronics or household items in. Growing phenomenon described in the Pittsburgh Gazette and popularized by Stephen Colbert.

Ironically, he got so caught up in wrap rage that he almost sliced off his finger using a screwdriver to open the package containing an X-acto knife.
