Replying to Define: Corks

I'm sort of having trouble wrapping my head around what a cork is exactly. I can identify one in any video, i'm just not sure how to explain it to someone it words. I skate board so when i learn a trick like a 360 flip for example i know that it is a combination of a 360 shove it and a kick flip. Then i can combine both of those tricks in my head and visualize what it would look like under my feet. Next season I would like to try corks but I'm having a hard time visualizing what it would look like from my point of view. This is probably a dumb question so i expect some hate but I couldn't find anything in the search bar. Any help would be great! Thanks.
