Cupcake

A cupcake was a form of baked food that originated with Human civilizations on Earth, a single-serving cake that is baked in a small cup-sized container. Cupcakes are often frosted with sugary toppings, just as full sized cakes are.

In an alternate reality, once provoked a bar fight in Iowa by calling an over-aggressive Starfleet cadet "cupcake", as a diminutive nickname that was taken as an insult. The same cadet graduated from Starfleet Academy at the same time as Kirk, during the Vulcan Crisis, and got a chance to use the term as an insult to Kirk—while arresting him for trespassing in engineering aboard the USS Enterprise (alternate reality). 

In the late 2250s, USS Fortuna Lieutenant Kathy Li also used "cupcake" as a nickname, for her lover, Lieutenant William Riker. When Riker was reassigned to a posting on the surface of planet Betazed, Lieutenant Li baked him an actual cupcake for their last night together. ({{n|TNG|{{nd|Imzadi}})
