What is no bonebone pressed

I’m lost, thanks.

It means you measure your penis from your fat pad to the head of the glans as opposed to pushing, say a ruler, all the way in until you touch your bone. The reason for bone-pressed measurements are that no matter fluctuations in your fatpad, you will be able to make conclusions as to whether or not you have had definitive gains.

What is “bonebone”?
