When someone goes into you on a water slide. e.g the rapids, lots of people go down at the same time and someone gets crushed
Extreme Whaling: a very big person squishing you
Dude 1: aww dude, he just got whaled, did you see how squished he was?
Dude 2: yeah i know,those water slide rapids can be brutal
