Something I came to realize awhile back is that my generation has an interesting tendency to use adjectives as nouns, such that they refer to an unidentified something that displays that quality prominently. For example...
- "Mind the gooey on the floor"
- "Well, that's a happy"
- "You've got a sticky by your ear"
Often, the adjective is preceded by a pause while the speaker tries to figure out what they're actually talking about... but not always. Sometimes it is only really that quality of the object that is important.
