1-up 

1. An extra life(or extra man) that you need in order to progress through a video game. In fact, you'll need enough of these to make considerable progress. Especially if you suck at the game. 1-ups are usually risky and difficult to obtain as items.
2. Also can be another term for sexual intercourse. Shortened form of "1 dick up (one's) pussy or ass."

Damn, Mark sure has a such a quick reaction time and alot of luck to beat Mario Bros on his first time playing it. He beat the whole game singlehandedly without relying on any 1-ups he earned! Mario surely must be happily spending all those 1-ups on Princess Toadstool in bed at this time!

OR

Damn, Mark really sucks at Mario Bros! He can't even get past the first level no matter how many attempts and always uses up his 1-ups! Mario must surely be getting all his 1-ups back indabutt from Bowser in his dungeon at this time!
