What is Hivin'?
1.
Multipurpose verbage used to describe an intense emotional state of need, excitement or immersion. Similar to
from 'Hivin on MT': "I been hivin on MT / doggin your friends / hangin down at the strip mall"
but also "Hey man what you up to?" "Oh, just hivin' out on some PHP toots"
and even "Quit hivin' me!"
