Stinky Software
Embedded firmware which was designed quickly and cheaply, causing erratic and unpredictable behavior. Examples include a DVD player which needs to be unplugged after it locks up, a cellular phone which has to be rebooted after it refuses to respond, or a hotel elevator which stops at the wrong floor.
The bus driver informed us that the automated announcements occasionally provide the wrong information. I told him, "Sounds like you have stinky software."
