look up any word, like bukkake:
noun; a bag carried by a strap on your back or shoulder, not to be confused with the word backpack which is completely wrong and sounds silly
sarah:"hey check out my new backpack"
chuck:"no no sarah..that is a bagpack...don't get them mixed up"
sarah: "hey you're right"
