"expugn"
Apparently a blend of expunge and impugn.
-Louise Pound's Second Word List from Nebraska, c. 1916

Birthday of Charles Lutwidge Dodgson
(1832-1898),
...better known as Lewis Carroll. Besides being the author of Alice's Adventures in Wonderland, he might have been the first to intentionally produce a "portmanteau word," two words interwoven to make one. In Through the Looking-Glass and What Alice Found There (1871), he coined chortle, the enduring blend of chuckle and snort [snort does not refer to snorting cocaine, which might result in snorfing the cocaine through the nasal passages whilst laughing -Shane]. Since then, many portmanteau words have turned up, particularly in America*, such as infanticipate, (to anticipate a baby's birth), coined by gossip columnist Walter Wenchell. Others from the early decades of the twentieth century include: snitzy, from snazzy and ritzy; frateriority, a college organization with both male and female members [also known as a beer-crazed orgy -Shane]; Broadwayfarer, a New York City hustler; scandiculous, a mix of scandalous and ridiculous; ... and [my favorite -Shane] solemncholy, from solemn and melancholy. Today this whimsical form is common, especially in advertising and newspaper jargon--drawing inspiration from terms such as adverteaser [good too! -Shane], which as long as eighty years ago meant an ad that aroused curiosity by witholding information.
*[I believe this practice is huge in the Japanese language as well, and common in many cultures. -Shane]
