Alabama mudknuckle 

The act of cramming your finger (at least to the 3rd knuckle) inside of someones 4th eye. If done correctly and your partners 4th eye is left quivering, your finger should look like an Alabama Mudknuckle!

I will never stop hitting that 4th eye until my finger looks like an Alabama Mudknuckle!
