Address Adultress 

When your spouse claims to not be having an affair. However, a wedding invitation is delivered to your home addressed to your spouse and some other random person's name on it. Not my name, but my address! What the hell?

My spouse is an Address Adultress as a wedding invitation was delivered to our home. My spouse's name was on it and some random person's name too. Not my name Buddy?

adultism 

If you believe adultism is right, you might as well thumb me down before going on.

1) The belief that adults are superior to minors. It is so widespread and common that most people don't even know adultism exists.

Corrupted scientists use junk science (incorrect scientific facts) to try and justify adultism. Unfortunately, it works.

Most people think pictures of an adult's brain and a teenager's brain can be compared to argue that adult's are superior in every way possible. -_-

Angela: May I participate in this homosexuality debate?

Adult: No, you are just 16 years old. Your brain is not developed enough to debate in this adult topic.

Angela: -_-

*and some more adultism*

Tom: Why can't I watch Family Guy, dad?

Dad: I want you to stay as innocent as possible throughout your childhood.

Tom: Epic fail!
