Slip Dogg

When you tell someone something important as a secret and they casually bring it up in conversation without thinking, with the person(s) that should not know in the room with you

If you secretly tell your friends you have a girlfriend and your parents don't know as the uptight bastards may try to keep you from her until they think you are "ready" for that kind of committment.

You and your buddies are sitting around your house just chilling and your mom walks in asking what you are doing tonight and your friends casually make fun of you and asking, "Are you gonna leave us for your GIRLFRIEND?"

You then say, "What are you talking about slip dogg?"

Your mom then says, "Everyone out NOW!" and then you proceed to put your story on FML.com
