I’ve opened up a can of beans

This is a mash up of “”can of worms” and “spill the beans”.  Of course, by itself it could be meant literally as opening a can of beans, but in the context the speaker meant to say “I’ve opened up a can of worms”.   This malaphor is similar to  a previous malaphor post – “That’s a real ball of worms” (12/18/12), mixing “can of worms”  with “ball of wax”.  Thanks to Denita for sending this one in!
