the gusty bus

A situation where further argument will not change anyone's mind about an aesthetic preference.

A corruption of the Latin phrase "de gustibus non est disputandum", also "there's no disputing about taste" or, more familiarly, "there's no accounting for taste".

No matter how much you hated Synecdoche, NY, you can't make me think it was a bad movie, so I guess we're riding the gusty bus.
