Alex Trebek had harsh words for one "Jeopardy" contestant on Wednesday night's episode.

The TV show host couldn't help but make a snide remark when librarian Susan Cole described her favorite genre of music: Nerdcore.

"[Nerdcore is] rapping about the things [nerds] love," the legislative librarian from Bowie, Maryland told Trebek. "Video games, science-fiction, having a hard time meeting romantic partners. It's really catchy and fun."

Trebek wasted no time firing back, "Losers, in other words."

Cole responded with a laugh, seeming slightly flustered.

"I'm teasing you," Trebek said before moving on.

Cole, however, got the last laugh. She beat out the competition and walked away with $22,600.
