That one person in your friend group that does not leave or know where to go so he just follows the rest of yous.
He has near to no social skills either, his mum probably sent him here.
Ryan: "whos that dude who keeps on following us around?"
Jason: "hes a backpacker"
"yo who is this guy?"
(back packer stares at the floor)
A security guard/officer characterized by an excessive accumulation of equipment and gear affixed to their vest or person, often surpassing practical or necessary requirements.
The security guard, armed to the teeth with gear, looked more prepared for doomsday than a shift at the mall—a real security "backpacker."
When you put random inanimate objects in your partners butt for fun, with no lube.
Dorothy and I are going to try out some extreme backpacking this weekend. Would you like to be apart of the insertion?
When someone comes to your spot dumps out their backpack all over your stuff and then slowly packs her backpack up with all your stuff and their stuff together and leave
Why you coming over here backpack barffing that s*** somewhere else
Backpack barfing is when people come to your spot & dump there backpack out all over your stuff & when they pick there stuff, they take your stuff along with yours when they leave.
Don't come in here backpack barffing,at my spot
When you get so blacked out you piss your bed and someone puts a backpack around your dead corpse and drags you around the floor.
"Dude, Brock was backpacked last night it was fucking hilarious"
