One of the ways to rate fanfictions. The citrus scale goes: orange, lime, lemon, and grapefruit. Though some people add other fruit in, it is mainly just those four.
Orange: Sort of the equivalent of PG-13. Doesn't really get beyond kissing
Lime: less explicit than a lemon, but still has sexual content. Characters do not have sex in a lime, but it is pretty close.
Lemon: Probably the one you will hear of the most. The characters in a lemon have s-e-x
Grapefruit: This one has two definitions. One is a really weird lemon or lime. The other is non-consensual sex. The second definition can be written as g-rape-fruit sometimes.
Pie1: hey, what is that story pie3 is writing on the citrus scale?
Pie2: errr...lime Pie1: WHY NO LEMON
Pie2: you're weird....
A drink only liked by a few people. It is a mixture of orange soda with water. At first taste, it tastes like orange soda but then disappears into the softness of water. This gives you a half and half taste and kind of teases you to want orange soda and water. It makes you feel light headed in a way from the rapid changes in taste. Why dont you just drink water? or Orange Soda?
Guy 2: Yo let me try it *takes a sip*. Yo it tastes like orange soda and then water its not that bad. *a few sips later*. Yo this is nasty. *pours away the seltzer water*
Guy 3: The Guy 1's in the world would be devastated seeing you do that
