Lampertum!

"That which initially impressive but, upon further consideration, was found to be distinctly less so."

Spread the word. Literally. Lampertum!

So as to facilitate comprehension and dissemination, I'll give a few examples:

• Sadly, Mary's date turned out to be rather lampertum, as became evident when he chipped her tooth while trying to make out with her.
• The concert was lampertum, especially because the lead singer persisted in belting out lines in spite of his distinctive bronchitis.
• See also: The Mullet. For one approaching a mullet-wearer from the front, the experience may be lampertum.
