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.

Manchester's local chav set gave Edward a poo in helmet last week. He didn't bother cleaning it before he put a photo of him wearing it on Faceparty.
