Now, I know I'm showing a terminal case of ignorance here, but what the heck is "ship" in this context? Is it anything like "grok?"
I'm not sure what "grok" is, but I know "ship."
'Ship is short for relationship, and has since become a verb in many fandoms. To "ship" Lois and Clark means that you're a fan (diehard, even?) of their being together.
Shipper is the noun. I'm an L&C shipper. As in the Smallville fandom there are, for example, "Clana shippers," which essentially translates to people who want Clark and Lana to be together.
