Go Away Jinx

Tear a small square of paper, letting your actions be as hard and angry as you wish. The paper doesn't have to be neat. 

When you've ripped the paper, write the name of the person who is irritating you. 

It works more when that person is near you, but you don't have to be in the same room. Doing it in the same house is good enough. 

Take the paper and stomp on it nine times. Stomp on it as hard as you need, let yourself be angry and annoyed and furious. Shove at the person who is annoying you with your mind, and let your energy push them out of the house. Do all of this at the same time. 

If you've sent enough negative energy their way, I have no doubt they'll pick up on it.

For good measure (optional) burn the paper, but screwing it up and throwing it away will work just as well.  

(Did this myself on an unwanted visitor in my house, stomped on his name, sent the negative energy his way, and he left fifteen minutes later, bag packed and everything.)
