Silly Game Time: I Grant You The Power To Escape Any Unwanted Interaction By Use Of A Magic Word. Whenever

Silly Game Time: I grant you the power to escape any unwanted interaction by use of a magic word. Whenever the word is spoken, you will disappear from your present location and reappear in the nearest public restroom that is at least 1/2 of a kilometer (or about 1/3 of a mile) away.

Which word will you use (keep in mind that the magic will activate whenever anybody or anything in your presence uses it)? And what will be the visual effect of your disappearance and reappearance?

Warrior and the effects would be that when I disappeared black smoke will surround on both sides of me then all of the sudden suck me into the darkness like a black and same thing for when I reappear except it pushes me out instead sucking me in.
