"Sexual innuendo is a hard topic to stay on top of. As a humor tool, it stands erect in the English language. While there are no hard and fast rules as to what constitutes sexual innuendo, many people have mass-debated over the ins-and-outs of the topic, and now the general principles at the root of the topic are firm and well-rounded. However, full penetration of the subject requires that the reader take a long, hard look at the target and be a cunning linguist in order to avoid limp phrases and imbibe the phrase with a large handful of meanings. The topic can become hot by attempting to grasp it, and the more one experiments with it, the more interested they become. Also, as the language changes innuendos must change in order to fill the newly created holes and satisfy listeners.
A common problem with sexual innuendo is the recipient being unable to wrap their hands around the intended meaning. In this case, an individual using sexual innuendo will often start slow and eventually build up, increasing depth more and more until the recipient feels the actual thrust of the point and the innuendo climaxes. An innuendo is always the most pleasing when no one sees it coming, often by entering the mind through the rear. Some skilled people are even able to use several sexual innuendos quickly in succession, resulting in multiple innuendo-esque climaxes. Key phrases can grasp the sentence by the ankles and part its long clauses allowing the orator to penetrate the essence of the sentence. In this regard, the key is to avoid stiff, rigid words, for ones that give the meaning of the sentence a firm rise in innuendic possibilities. Some regard sexual innuendo as an art form, and it goes without saying that one needs a certain level of oral skills in order for the fluidic exchange of innuendo to succeed. However, this is not enough to fill the requirements. One needs to pay special attention to the region of the sentence to which the innuendo will enter. For lasting effects, it is most important to enter deep within the recipient's consciousness and to ensure that all of the seeds of humor have flowed forth. This is not an easy task for most people, so it is only through rigorous repetition of the insertion of sexual innuendo that one can fully master the uplifting effects it can have on vocabulary.
On another side note, one must remember that when practicing innuendo to somebody who has heard it for the first time, one must be ready to slowly enter in the tight quarters of the reader's mind, lest risk getting their ideas unpleasantly stuck within the annals of the reader's mind.
Although sexual innuendo requires masterful manipulation of parts of speech (and sometimes the skillful use of body language), for most people it comes quickly. There is currently much debate over whether an extended innuendo can substitute for technique."Reference
