intracranial flatulation

The politically correct version of the more coarse "brain-fart" - suitable for use in business settings, testifying before Senate subcommittees, public speaking engagements or other instances where "brain-fart" might prove to be offensive to sensitive parties.

"I apologize, Senator, my recollection as to how the three billion dollars was misappropriated escapes me at the moment - I'm sure it must be here somewhere - I'm clearly suffering from intracranial flatulation."
