Asking someone to smile, then squeezing their cheeks together and yelling sex face before laughing uncontrollably.

You may also wait for the person to smile at random then perform this special move, this is useful if a person refuses to allow a sex face to be performed on them when it plainly should.
"Lewis was smiling alot so, when he least expected it, I sex faced him."
