When you're absolutely wasted and can't get your dick up, but you need to fuck a chick. You pray to Jesus for a solid erection and he comes through like a bro.
Q: Hey, what are you doing in church?
A: I was smashed the other night but needed to fuck this chick, so I prayed and God tossed me the greatest Jesus Boner I've ever had. Now I feel obligated to go to church.
