Harry Potter: Draco+Harry *dude, I'm not kidding*
SpongeBob: SpongeBob+Patrick *still not kidding*
Star Trek= Kirk+Spock *you know...*
ABC's "LOST", is a perfect example of this annoying trend. The Jack/Kate/Sawyer love triangle have generated many shippers that call themselves "Jaters" (Kate/Jack relationship) or "Skaters" (Kate/Sawyer relationship). The shippers are occasionally mentioned and somewhat mocked by "LOST" producers Damon Lindelof and Carlton Cuse.
A "ship" usually gets its name by pairing the first letter of the male with the female's name, or vice versa. I.E. Brangelina.
