The tasteful combination of headbanging and smanging (the combination on smashing and banging). Headsmanging is the best dance move, sex position, and way of life put together. Must be done naked. If you're not headsmanging, you're probably a lifeless virgin.
"Man, I saw Lauren at the club last night and she was headsmanging all over the place. I fucking took pictures."

"Damn, Mr. Grossman's attempt to headsmang is really pathetic....he's still wearing his underwear. what a stupid fuck"
