I find that often when speaking my brain is trying to select from a set of words and can't choose quickly enough, or moves too fast and merges them together in a new concept while no one else got to see that logic train pass by. ;) The result is these kind of word mashups.

Sometimes this goes badly. Like the time I meant to tell a co-worker that he looked nice all dressed up in his suit, but my brain couldn't decide between "spiffy" and "snazzy" and kept bouncing back and forth... spiffy... snazzy... spiffy... snazzy... spiffy... snazzy... and it came out:
"wow, you look spazzy"
*cringes*

Sometimes it results in new words of the onomatopoeia variety or better words to describe the situation. Such as my brain salad concoction that spit out the phrase:
"that's so Orson Wellian"
...not "Orwellian", but the drama of Orson Wells with the futuristic forboding of George Orwell. ;)

Does anyone else have this "problem"? :)
