func'd 

The feeling after you have exhausted yourself and you know that you went hard as you can go. You against you.

I have just finished ZUU and I am now func'd!
I'm func'd!

too drunk to func

1) The act of becoming too inebriated to physically perform any tasks. 2) Not being able to perform sexually for reasons of being too inebriated.

Damn Billy was too drunk to func last night, I can't believe he tried to make that pizza.
