Get the glowbuttmug. To "slug"somebody is the non sexual act in which the slugger holds someone down and then proceeds to slide their penis across a persons face very slowly so the person feels the mans genitals squished against their cheek, nose, mouth, and forehead.
Billy dipped his penis in petroleum jelly before he began to slug his buddy Mike, which left a penis trail across Mikes face.
