When a male smears his penis in shit and repeatedly cocksmacks his girlfriend, usually performed in a construction site porto-potty.
Yeah, we were working on the new municipal building and I gave my girlfriend the old Sludge Hammer during lunch break.

When a male is about to ejaculate during sexual intercourse. He then will pull out and bring his cock forward to the females face. The male partner then times his ejaculation and smacks the female in the face with his cock, while simultaniously blowing his load all over her face. (NOTE: This requires near PERFECT timing!)
I sludge-hammered her freaking face last time. She couldn't freaking see! & I think i gave her a black eye..
