Words that Roll Trippingly Off the Tongue

From AllEyesOnJenny comes this unabashed word-love:

Once I did a list of the grossest words to say, now I’m countering that with fun words to say:

Onomatopoeia
Cacology
Nuance
Undulate
Symposium
Loquacious
Facetious
Phlebotomist
Superfluous
Trabajabamos** (Yeah I know it’s Spanish, but it still applies.)
Nefarious
Abominable
Discombobulate
Disingenuous
Lackadaisical
Archipelago
Guacamole … closely followed by …
Avocado
Oblivion
Usurp
Plethora
Shank

Lindsay and I discussed this carefully, and we would add:

1. Perspicacious
2. Discombobulate
3. Zinfandel
   
4. Whimsy
5. Scuttlebutt
6. Smack
   

Aidan contributed:

1. Marshmanannow (similar to a "Marshmallow," but with more complex flavors)
   
2. Vanderhorst
   

Asher added:

1. Ga Ga Ga Ga Ga

He's such a Spoon fan. However, we voted to take exception to "Trabajabamos." Very questionable... True, it is a lot of fun to say, but it has no English usage, and the Wikipedia entry is absolutely no help. Out!! ;)

What words would you add?
