Flup

Flup is a thing to which the Melnorme equate something that is easy. The most notable, and only, use of flup is in an exchange between Trade Master Greenish and The Captain, wherein the former explains the ease in finding a male of the Shofixti race by saying that "[it] is easier than flup."

It can be reasonably assumed that flup is likely a game or sport of Melnorme origin.
