Another wonderful word:
3. Shifty or tricky.
4. Smooth and slippery.
How can this fun and fabulous word, lubricious... Let's say it together: Lubricious!... have a negative meaning? Its flavor should be closer to delicious than to lecherous. I wish I could change the definition of words to suit me.
