A covert technique used by men during sex when you reach behind and pulls your ball sac back and away from your body; this action enables your penis to extend forward hence revealing your hidden penile inch. Most effective on women you fuck for the first time and during doggy style when your partner is unaware of your activity.
I fucked my girl good last night, I gave her the hidden inch!

That bitch thinks I have a big dick but I fooled her with my hidden inch!
