Mayonnaise Backpack

When you pull out during sex and cum on someone's back without telling them so they lay down and smear semen on their sheets.

Did you hear about Drew's girlfriend dumping him? Yeah man, he gave her a mayonnaise backpack and she ruined her sheets. 1,500 thread count, bruh. That's not cheap!

blackjack

A card game where you basically try to beat the dealer by getting as close to a total of 21 as possible without going over. A picture card and an Ace counts as 21, or Blackjack. This is one of the best games to play when you are in a casino given the low winning advantage of the house.

If the tourists spent more time playing Blackjack, Poker, and Craps, and less time playing the slots, the casinos would be making a whole lot less money.

Backpacking

When one soaks a tampon in liquor then sticks it in there anus to get drunk. Backpacking is extreamly dangerous because you dont know how much alcohol is exactly getting soaked up into ur bloodstream. But it gets u hella messed up.

I really want to get shitfaced tonight but only have a few shots of vodka. Looks like im backpacking again.

Whenever im backpacking i always end up naked in my dads bed...

Backpack boys

Backpack boys are a group of pubescent wannabe hype beasts. They wear large backpacks that are much too large for their teenage bodies. They travel in packs, and all mysteriously look alike, but they are NOT related. They never seem to talk, just walk around with their big backpacks. The term “backpack boys” was coined by Daisy Baierl in 2019.

nobody: “I’m going to go sit with the back boys”

Nobody: “The backpack boys are hot”
