Goto next slide"Voluptuous"

When:

Lookups on Merriam-Webster spiked on November 28, 2010.

Why:

The American cables revealed by WikiLeaks included the not necessarily diplomatic detail that Libyan leader Mu'ammar al-Gadhafi travels with a "voluptuous blonde" nurse.

Voluptuous means "suggesting sensual pleasure by fullness and beauty of form" – in other words, "attractively curvy."

It comes from the Latin word for "pleasure."
