Backpacking 

In the case that your friend is blacked out drunk, fill a backpack with textbooks and roll the person on their side to prevent them from choking on their own vomit

When Jake passes out last night we used backpacking to keep him from choking

Spoon Backpack 

When being spooned so tightly it's almost like a backpack.

He let me spoon backpack him all night.

Backpackistan 

The country that exists in the minds of twenty-something-year-old travellers throughout the entire world. It's citizens are identifiable by their dreadlocks, faux-tribal tattoos and strict, tiresome adherence to a Bob Marley tunes. They eat falafel and juggle fire torches. Their economy is based around mooching, and the sale of Tibetan prayer flags and Che Guevarra marijuana pipes. Backpackistanis are united by a common language: broken English.

Even though I spent a year travelling through Paris, Madrid, Morocco, Bangkok, Bali, Sidney, Sao Paulo, Machu Picchu, Guatemala, and Southern Utah, I feel like the only country I really visited was Backpackistan.

Mexican Backpack 

A racial term to describe the leaf blowers that landscapers wear. Typically, the engine of this type of leaf blower is strapped to the worker's back while the hose runs down their arm to their hand where they can direct the air stream.

Whoa! Check out the Mexican Backpack on that guy! It looks like a 44cc dual-ring piston engine, and WOW a hip mounted throttle controls with cruise control. Now that guy can still work AND be lazy.

backpack inversion 

a fun game invented by the high school marching band drummers of berlin, ct (also sometimes practiced by Berlinites or a combination of both). basically involves the following procedure:

1: Aquire someone's backpack while they are not looking
2: Remove the contents of the main pouch carefully, being sure to keep everything in the same order (or disorder) as it was found
3: Flip the backpack inside out
4: Put the contents of the backpack back into the now inverted backpack
5: Zip it up and put it back where you left it

the victim of this pointless and rather humorous attack will be most suprised when he/she turns around and finds their backpack flipped inside out. the same attack can be practiced by taking the backpack from their hands and using force to keep the victim away, however, must be accompanied by continuously repeating the phrase "just let it happen.."

shmope: dude, let's do a backpack inversion with dome's backpack.
shmope's friend: ok!
*inverts backpack*
dome: wtf, you guys suck.
mike: hahaha, dome has a big head.
