Describes someone who gets really excited about something too early/quickly and jinxes you. (Also another term to describe a premature ejaculator.)
Wow! I heard that you might be getting that promotion! That's fantastic! I'm so excited for you! I've already told everyone I know!

Geez! Don't be a premature congratulator or you'll jinx it for me!
