Dactyl Backjack

Performing the ol' reach around on yourself, an advanced masturbation technique. Word origins can be traced to dudefuckinghellyeah (DFHY) at burning man 2009.

The stranger is getting old, I think today I'll change things up and pull a dactyl backjack when I'm wanking.

rolling backpacks

Swag on wheels, also know for making bitches moist

My friend and I walked into school with rolling backpacks close behind. I heard the bitches start to whisper and moan just at the sight of it. I knew it was going to be a good day for the two of us.
