When you really have to go poop but your wife, your girlfriend or kids do not want you to go poop because it will stink the bathroom.
Husband: Hey are you done with that magazine I really need to go poop!

Wife: Don't go and poop in there!! I need to do my make up! Wait till I get done!

Husband: Do not be a poop block!!!!!!
