This technique was invented by the people of Planet Yardrat. It involves locating the chi of someone you know with your mind, then teleporting right next to them. Son Goku learned this technique while there and used it to get around ever since. However it is limitted by the fact you can only teleport to people you know and sometimes you can be too far away to feel their chi.
