I found this really cool glitch a while ago so i decided to share it today

Get 2 people, both with atvs
1 atv should be slightly in the other atv (just ride into the other atv a bit)
1 atv should be slightly higher than the other, the person thats slightly higher than the other should go off and on his atv.
if you do it right you should fling really far and/or high
