Phrogging is a person secretly living in another person's home. The word is pronounced "frogging" and gets its name because phrogs, as the people who engage in this activity are called, tend to "hop" around from house to house, as a frog might do on a lily pad.
While drunk, you phone someone you can't talk to sober (because of bad past-times or because you haven't got the balls) and talk nonsense to them until they either put the phone down, or agree to have sex with you.
