banemasking 

The act of placing a pair of women's panties (preferably used) and stretching the leg holes around one's ears and positioning the gusset against the nose while deeply inhaling the sweet, succulent aroma. When done properly, it simulates Bane's mask in Christopher Nolan's "The Dark Knight Rises".

Zach: "Guys I found a pair of dirty panties in my laundry."
Werner: "DUDE, let me see those. I love banemasking a creamy pair of panties."
Zach: "Jesus,dude."

backmasking 

A term used by people when they reverse songs and listen for secret messages.
Songs such as:
-stairway to heaven
-another one bites the dust
-my name is
-oops I did it again

and more

When you play Oops I did it again backward in a part it's going to say "sleep with me I'm not too young"
