(hoh-RIP-uh-LAY-shun)
(n.) Goose bumps; bristling due to fear or cold

If you've used "goose bumps" too many times in one paragraph, you can always substitute this word, which derives from Latin "horrere" meaning "to tremble" and "pilare," which means "to grow hair."

"If you like horripilation, you'll love 'The Sixth Sense.'"
