A code called at Linden Oaks Mental Hospital. It's used when a patient goes completely ape shit and the only thing left to do is to lock them in a room and inject Ativan in their ass.

When a girl or guy stares at another guy or girl who they think is cute for long period of time (stalker like). This is to be used as a warning to warn the person that someone is staring into the very depths of there very soul for 5 hours without taking any breaks. Its is best to avoid a Code Yellow if at all possible to prevent any discomfort! To warn someone of a Code Yellow, just say "Code Yellow" or, for singal purposes, say "Yellow" in sign language.
