Portmantneau

Portmantneau: noun. Also sometimes spelled "portmantno". This is the word used, when someone takes two words and combines them in an absolutely horrifying manner, creating a lexicological abomination that causes hernias in dictionary-writers everywhere. The word is usually exclaimed at a volume of at least 500 dB, megaphones can be used if necessary or if your vocal chords are puny! Har har.
