50-50 

1) A 50-50 is a skateboarding/snowboarding trick where you jump on to a rail, and grind the rail with your body parallel to the rail. This trick is the base for 5-0s, Nosegrinds, Crookeds, and Salads.

2) A 50-50 on a pipe is where you come up to an Axle Stall at an angle, and get on to the coping in Axle stall style, then you slide along the coping a little, then you drop back in.

50-50s are a simple, yet tight trick.

50-50 

The 50-50 is a very mutual and sexual act performed by two people. To perform the "50-50" you will need to have a tub of Nutella and an anus. Scoop out a reasonable amount of Nutella onto the finger and insert into the anus. Allow 5 minutes rest and then with your tongue, lick inside the anus. There is a "50-50" chance that poo or Nutella will come out.

"Hey mum, can I 50-50 with the Nutella this week?"

"Hey babe, I was wondering if I can 50-50 you tonight?"

"The last time I 50-50'd someone I got poo on my tongue!"

"I'm not too hungry tonight. I might just have a 50-50."
