A word that means something different to each person who uses it. A person's home can be the place where they live, the place they grew up, or the place where the people they care about live. In the case of some people, home is a variable concept, changing dependant on the placement of another person or object, or a person may even consider his or her own body the only 'true' home.
A place that you feel comfortable in. Usually a home has family, friends, and whatever makes that person happy. A house isn't necessarily a home if there are no friends, school, job, etc. that makes the individual happy.
In relationships, "getting home" is to have sex with the other person.
(as an analogy of beisball, the different steps from kissing to actually having sex, have been compared to getting 1st,2nd 3rd base, and finally "getting home")
