"Poohbar" is something a mother loves to call her son (that he most likely doesn't want to hear, especially in the company of others). It is an endearing, affectionate term that some adoring mothers have difficulty removing from their vocabulary due to the fact that their child/children is/are so special.

Poohbar is a variation of the "Winnie the Pooh" character who is also known as "Pooh Bear."

when you've done something so cringe you can't stop replaying it in your head and it stops you from getting on with your every day life
