Dome Smash 

Dome Smash: To inflict damage upon a person's head (dome). Typically performed with an individual's fists and feet, more advanced techniques include exterior objects such as: poles, wood blocks, hammers and curbs. Similarly, there is a metaphorical dome smash. This is commonly used after a night of drinking to indicate serious intoxication and loss of memory.
