A bummer lamb is an orphaned baby
sheep that has to be fed with formula from a bottle. When you call someone by their name and add bummer, it means they
don't
like crowds and prefer to stay much to themselves.
The silly bummer won't go to the football
game because of the crowds.
Christy bummer rather watch old movies on
netflix than go to the theater, wait in long lines of
people, and have to sit by strangers.
