Robin Hood

The act of pulling the duvet over ones head tight like a hood going down on a guy or girl, being sure to keep the hooded legendary appearance dive in between the legs.

I was talking to my friend at the bar and he told me how he went full Robin Hood on this girl. I knew what he meant by the actions.

Guy: have you ever heard of Robin Hood?
Girl: I have green bed sheets, let's go back to my place.
