One
part of a pair that is so close that it seems as though
sometimes they are attached by an umbilical cord
Umbies - the pair of
people who are practically biologically attached
"God Margaret and
Max are always together, they need to
cut the fucking umbilical cord"
"No its ok, they're totes umbies and we've all learned to accept it."
"
Wow, I'm surprised to see you without your umbie"
