Similar to the Donkey Punch, except during climax, instead of punching the girl as hard as you can, you slam a barrel over her head.
So I was hittin' this chick up right,
and she was all into the freaky stuff right,
so I was all like "Yo, baby, let's do the donkey punch!"
But she was like "Hey, let's do something freaky--the donkey kong punch!"
Yeah. It was nice.
