Facebang - Using your face to give a woman head. It's like fingerbangin

Using your face to give a woman head. It's like fingerbanging, but with more tongue and less fingers. If it's two girls, it's extra fun.

She gave me a facebang and I almost passed out.

My girl gave me a facebang in the library and got caught.

My friend’s girlfriend facebanged him and now he's a legend.
