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")
A feeling of peace and nostalgia, seperate from a place or person that resides within the self. Often times a scent/smell (ie. Baked goods), a sound (ie. father whistling) or a physical sensation (ie. cat fur).
