Boob Zipper 

A shirt that has a zipper that goes across the breasts, which when opened, will expose them.

This is not something that is available in stores, but if you are fortunate enough to know someone that likes to design their own clothes, you may ask them to make one for your girl, wife, etc.

True Story: My sister received a shirt from her good friend that wants to be a fashion designer. The first thing that I noticed about the shirt, is that it had a zipper that went across the chest. I immediately termed it as a "Boob Zipper". I have joked with her about having her friend make one for my wife. Well, maybe I was not totally joking. I would like it very much. :)

That Boob Zipper Shirt is HOT.

men wear pants in the relationship, but women control the zipper 

a) a synonym phrase for "there are two sides (or more) to every story"

b) (forensic/criminal investigations, often used sarcastically): if you can't see the evidence, it doesn't mean it doesn't or can't exist.

c) (legal system): assuming that the defendant is not so severely mentally ill that even medications won't help, there is/should be/must be a motive to every crime.

d) a phrase meaning, everybody involved in the judicial system has their own motivations for acting the way they do.

based on the definitions above, especially definition d) CNN features a show called Death Row Stories because some prosecutors still need to learn what the phrase men wear pants in the relationship, but women control the zipper means.

The Zipper 

The zipper is a two handed sex move performed on a penis by someone else. Basically, while kneeling in front of your partner, you interlace your fingers grabbing the penis with both hands and rhythmically stroking it in a back and forth manner. This hand position is superior due to the added friction and position of the hands to apply more pressure with least amount of effort.

James said, "Wow that girl was skilled in bed last night, she performed The Zipper on me, Amazing".

Rob replies, "Damn your so lucky, I wish my girl knew about The Zipper".

Kevin exclaims, "Whoa, I gotta run back to the "love nest" and teach my girl The Zipper right now".
