Taro Icee Drink with Nata De Coco and Thelma Boba

"Grandpa, what is
backwash?"
"Well my little piece
of custard pie, that
is when you have a
drink of something,
and then somehow
some of that drink
finds it's way back
into the glass or cup.
It is usually just a
haze, discolorization,
or maybe a chunk or
two of something....
hopefully really really
small, but sometimes
it could be something
a little more meaty.
Just like this Boba
drink I got here.......
When I got it, it had taro shave ice, nata
de coco and just a few pieces of boba....but
your Grandma took a couple of swigs and now all
of a sudden it has a couple of inches of boba....what
the?.....where did all that boba come from? ......and
then I remember, 'Oh Yeah....Thelma drank it.....
Thelma Backwash.'"
"Ewwww, Grandpa....that's gross."
