This may be typical of my region only (Beira Alta), because many Portuguese people have told me they never heard this. But I did, many times. "Arrimar" means both to hit someone and to hit on someone. This idiom usually comes when you mention some female cousin of yours, and you're a man. Like "Dorothea is my cousin." And the person you're talking to says back, with a naughty look, "The more the cousin, the more you hit her".
