Not to be confused with a dick pic, a soft dick pic is a picture of a male's flaccid dick that is typically transmitted to a woman via sms or email. Women generally crave these soft dick pics and will typically perform fellatio on the male who transmitted the pictures the next time the two come in to contact.
