What's in a {NICK} name?

I think nicknames are so fun!

I guess I love nick names because there are always funny stories behind them.

And I'm a sucker for a funny story.
Our family members have some funny nicknames

Bean

my uncle Paul ate a lot of beans and then went to the movies

and I guess you can probably guess the rest

bottom line:

whole family and row behind left and went to the back of the theater

Tag

another uncle, Mike, has this weird habit

of rubbing the tags on his shirt he is wearing
or better yet, if you sit next to him-he might rub the tag on your shirt

Boo

Andrew's bro Brian was apparently quite the whiner once upon a time

he doesn't whine too much now--but the name is still there

Bosom

Becca {Bingham} Greenwood and I

used to love to watch Anne of Green Gables

so we started joking that we were bosom friends

now we still call each other Bosom

when my mom wants to know what's up with Becca, she says

"What's new with Bosom"

Dibb

all of Andrew's friends call him Dibb

and most of my family calls him that too

I called him Dibb {or "quiet boy"} until we got engaged

then I had to train myself to call him Andrew

just after we got engaged

my aunt Leslie called my mom and asked

"What's Dibb's last name?"

my mom said

"Dibb"

Leslie said

"Dibb Dibb"

my mom laughed and said

"Nope, Andrew Dibb"

Leslie replied

"Wow!  I had no idea"
