Meaning that you can see someone's butt crack or underwear slightly as a person is bending over similar to the zipper of a backpack being slightly open.

(Emily bends down to grab books) Me: Hey Emily you've got an open backpack
Emily: Did you notice my new Victoria's Secret thong?
Me: No I was just looking at your crack.
Emily: You're an asshole.
Me: LOL get it?

Dusty Backpacker

Dry anal. The receiving partner stands while the giving partner sits on a table or high chair behind them. The giving partner wraps their legs and arms around the receiver, who then steps forward and carries them like a hiking pack. Penetration ensues.

Popular among feminists and power bottoms.

"I gave Jill a dusty backpacker last night. We ran out of lube but she's been doing squats lately so it turned out alright, dude."
