In a funny moment during the live commentary of the PokerStars EPT Barcelona final table, commentator Jason Mercier launched a new term for the poker dictionary - or, a new one to this writer at least.

It occurred in a hand between the Romanian Mihai Manole and the Spaniard Santiago Terrazas. When play was folded to Manole in the small blind, he pushed all-in with his short stack, and Terrazas paused to think things through.

As Terrazas asked for a count but still hesitated, Mercier figured the tight Spaniard was tanking with a hand he should call with quickly, and explained: "It's not a slowroll, it's a nitroll. He's not slowrolling him, he's just a tight player."

Inventing new hilarious words is not all Mercier (pictured) has done in the poker world. In a short but very impressive career, he has already won a WSOP bracelet, EPT title, EPT High Rollers event and collected a total of $3.3 million in tournament cashes in just 18 months.

(For the record, Terrazas finally elected not to call and mucked his hand.)
