Simple. When a guys dick doesn't fit in a girls pussy cause she's just too tight.
"Babe it's just not going to fit"

Distance Distortion Factor. When a girl looks hot from a distance but isn't when you get closer.
"Dude, she looks hot"

"Nah mate, it's just DDF. I've been closer and she isn't."

A DECA doll face or DDF refers to the best type of DECA girl you could ever meet. She is amazing, witty, beautiful and hillarious. This type of women is very prominent in the business world and sets high standards for herself. She'll probably be your boss someday.
the best type of DECA girl you could ever meet; not a DECA slut

DDF is a look on the face similar to RBF but with an added rancid, un-groomed taste of a dirty, bitter possibly un-cut dick lingering on the taste buds.
