A word that is much similar in spelling and meaning to "Badside." This word can be used to describe something that you would normally NOT tell your parents.

It is not uncommon for someone to create a "Bdsd" account on facebook, to post pictures of them doing things they shouldn't be.
Me to friend: "You man, I smoke weed all day, and I don't give a SHHHHYYYYT".
Friend: "thats great dude."
Me: "Oh and keep that on my bdsd ok, thanks."
