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.
