Bingo

A totally bad-ass game where some dude with a microphone calls out a letter and a number simultaneously and you mark the combination on your board if it's there. After playing this game for about 10 minutes, someone will get 5 pieces diagonally, horizontally, or vertically and yell out the word "BINGO!" and everyone will applaud and they win the game. Generally only played by old people with no lives.

Put-down or criticism of a life choice.

When you are lifeguarding, and you accidentally, or intentionally, let a whole family die in one night.

An exclamation used when you finally work something out, or an idea/solution suddenly comes to mind. Also said when you discover somthing.

A person who carries the whole team on her back and scares the opposition

An alternative way for saying "that's what she said" in public. Only to be used in situations where saying that's what she said would be deemed inappropriate.

An urban term used throughout Australia to describe an ecstasy pill. It originated in Perth and was made notorious by a large community of druggies starting in 2003. It was meant to replace the words such as pills, ecstasy tablets, poppers, and flippers, all of which mean the same thing, but have a negative connotation. Basically, anyone using the term Bingo was considered elite. As such, today it is used liberally by many party-goers in Oz, although the appeal of the word "bingo" was based around the fact that not many people knew what it meant and that it required explanation. It also helped justify the use of the drug since it was suddenly "hip" to explain the exclusive bingo talk.

Explaining the word bingo always brought a smile to the face of the noob who did not know what it meant. It did have a 100% conversion rate - once you hear bingo, you never call the drug anything else.

It was also common to call your elite buddies by their "bingo" names. A bingo name is basically the word bingo, followed by a single word describing the person. For example:
anti-bingo: someone who does not approve of the drug use
bingo man: when you need bingo, he's your man
bingo party: someone who is hooked to bingo and good times
bingo barbie: a pretty druggie
bingo wiseman: someone who knows everything about the bingo experience
bingo veteran: someone who has been taking bingo for 10 years+
bingo milkybar: a cute person who drinks milo by day, and has a bingo every 6 months or so
bingo machine: a bingo dispensing machine
