thrashturbate

The act of simultaneously masturbating and hardcore dancing.

"Holy fucking shit, this Throwdown is so good."
"Yeah it makes me so hard it's scary."
"Let's thrashturbate, Bro."
"Isn't it gay if we do it together?"
"NO IT'S FUCKING HARDCORE!"

trashturbate 

The act of masturbation to 'dumpster porn'.

I caught my friend trashturbating to the Playboy I threw out yesterday.

I never trashturbate, I use real porn.
