look up any word, like spook:
To have someone deliberately draw the attention of a being of hostility to themself, and then go near their victim (so as to alert said hostile being of your presence).

Usually, the offender also pretends to be dead (or completely vanish), in order to disinterest the aforementioned hostile being from them completely leaving their victim in danger.
Victim: I was just minding my own business when some rogue with a vicious mountain lion chasing him ran at me and vanished!

Victim's Friend: You got rivaled!
