mad air 

when a car, bike, motorcycle, etc. is traveiling at high speeds and jump off of a ramp and goes very high in the air.

1."Dude that guy is getting mad air".
2."I wanna get mad air".

mad air jump 

When you swing back and forth on a swing then on your final swing out you release and propel your body forward and away and try to retain your balance as you land on the ground.

Crazy Johnny did a mad air jump off the swing and when he landed on his conchy joe butt.
