My adult daughter and son often call me to catch up on what is going on...and...quite often...I hear a toilet flush in the background. That's when I start shrieking "You're talking to me and pooping too??!? Again??!? Really??!?

So I just started thinking that in this crazy hectic life that we live...it must be really hard to find time to fit in the really important things...Like:
CALLING MOM.

I just came up with the word: Moop or Mooping: Calling Mom whilst making a Poop!

This definition could be placed under two different categories: Multitasking and Pooping.
Wife: (shouting from the kitchen) "Babe...Dinner's ready!" Husband: (responding from the bathroom) "Be a few minutes Honey...I'm making a Moop!" or "I'm Mooping, Hon...It'll have to wait!"

Cherry: Why, yes. Gymnastics was my thing a few years ago, so they had to be flexible. I use lip balm, so my lips are pretty soft...

Xavier: Perfect. You. Moop. Now.

1) When you are feeling like utter shit, but are in a situation where u can't say Shit or any other word you ACTUALLY would say in it's place!

2) Complete Mopeyness

3) Feeling Down

Can add other nonsense words on the end to give it a real shitty boost.... Note: Using "Moop" on it's own along with a real "feeling sorry for myself" facial expression will be more effective at getting sympathy!!
I'M NOT DOWN....I'M WORSE THAN DOWN {long pause} i'm totally moop today!!
