Helmet Liner 

The creamy, cheesy, odiferous amalgam that forms a ring around the base of the glans or bell endaka helmet of the penis. The amalgam may also be referred to as shrimp paste, smegma or duck butter. Helmet Liner may be hidden from immediate view in the case of an uncircumcised member and becomes visible during a Ripe Banana Peel Back. Helmet Liner is typically formed from pure, unadulterated penile filth.

Frank offered up his dirty dick to a prostitute on the way home from work. For $5.00, she happily wiped away the Helmet Liner from his bell end and commenced a sloppy wet hot gummy.
