Similar to the Rusty Fish Hook
but named after the Professional Czech Hockey Player. While satisfying your lady from behind you abruptly jam your finger into her poop chute. When she turns around to yell, "Hey!" instead of giving her a traditional fish-hook
you cross check her in the face with a hockey stick. For additional bravado you can then shoot your load on her back, blow a whistle, throw your arm in the air and declare that you're giving yourself a 2 minute minor for roughing.
My girlfriend told me that I couldn't finish watching the game until I finished her, so I gave her a Rusty Klesla and then went downstairs to finish watching the game.
