According to FUNKTIONARY:

PROP – People Running On Programs. You have been programmed. With few exceptions, we have all become “Rolebots” acting out our expectations communicated to and created within our psyche by society and the dominant culture. Prop is truncated for “propaganda.” We are “rolebots” (mechanical slaves to our programming) with our body-minds thinking, talking, and acting along conditioned paths (with predictable outcomes) unable or unwilling to edit or even remove (override) our head-tapes and deviate from our subroutines.
