When something is SO LAME that it actually comes full circle and becomes AWESOME again; something so bad it's good.
(Named after the notorious but fun cheesefest movie The Cannonball Run, starring Burt Reynolds.)
Not to be confused with something which is both LAME *AND* AWESOME at the same time, which is LAMESOME.
- Man, that film was AWFUL!
- Oh, come on, it was a BallRun!
