Nearly every profession has its own secret emergency codes which are used for brevity in time sensitive situations and, occasionally, to help prevent panic among the general public.
These codes can be anything from random, unrelated words to the name of a generic person, and are typically only used to fellow members of staff in the know.
They are used in shops to make security aware that there is a shoplifter or suspicious person on the premises but they are more common on public transport.

- If blood needs cleaning up
- If there is urine or poo that needs cleaning up.
- If anybody should vomit and that needs dealing with.

This can sometimes involve officials shouting 'freeze' to scare passengers and locate the source of a threat.
Once you are on board an aircraft, here are some codes you definitely don't want to hear.
