   BLOB
   
       1. n. [acronym: Binary Large OBject] Used by database people to refer to
       any random large block of bits that needs to be stored in a database, such
       as a picture or sound file. The essential point about a BLOB is that it's
       an object that cannot be interpreted within the database itself.
       2. v. To mailbomb someone by sending a BLOB to him/her; esp. used as a
       mild threat. “If that program crashes again, I'm going to BLOB the core
       dump to you.”
