Listen up, chucklehead! This "I cup" business is a play on words. The dude is asking his friend to spell "I cup," which sounds like "I see you pee." The joke is that the friend is catching the speaker peeing, which is why the speaker wants some privacy in the bathroom. You would have never figured that out, you silly goose!
