|Citrus is used to describe the most mild interactions on the scale, such as a romantic hug or a kiss on the cheek.||2.||Orange|
|Orange is used for kissing, hugs, and some more touching beyond that that begins to have a hint of sexuality.||3.||Lime|

|Lemons have actual sex.||5.||Grapefruit|
|Occasionally, a fifth fruit (well, fourth, since citrus itself isn't actually a single fruit) is added. It is generally said to be the X-rated or truly bizarre lemons, but it is not widely used. At any rate, it might be discouraged from inclusion in the Citrus Scale for PPC use, as it might cause flashbacks of "Celebrian" in unwitting agents.|
