Low side is when your front understeers out from under you - imagine the front washing outward sending you tipping to the low sid of your lean as you enter the bend.
High side is when you are exiting the bend under power, and the tyre is spinning up and slides towards the outside of the bend in an oversteer condition - then suddenly regains grip flicking the bike upright and catapulting you over the highside of the bike outward toward the outside of the bend.
The flick can be very violent and send you up into the air and sending you crashing down breaking shoulders, necks, ribs etc.
A highside is pretty violent even though it is a relatively slow accident - it is the violence of the flick, that if you dont' catch it and kep you hands on bars send yo flying.
Corpse came out pretty lucky - I would rather catch the slide, survive the highside flick and shoot forwards and then wreck
