They're Thirsty. Apparently.

 

Possibly thirsty youths.

"They're thirsty," says Tom waving his arm vaguely in the direction of the television. On-screen, I see a bunch of twenty-somethings lounging around in a restaurant or something.

"What?" I say. I have no idea what he's talking about.

"They're THIRSTY," says Tom. Louder this time like he's talking to someone with English as a second language.

"I don't get it." 

"It's slang," says Tom, very knowledgeably.

"Yeah, I picked up on that." 

Tom shrugs. "I don't really know what it means, actually."

"You gonna look it up?" I ask.

"Nah," says Tom.

"Me either."

Addendum:

Tom read this post and states for the record that I have inaccurately captured this incident. He claims he figured out what "thirsty" meant long ago. Like ages. It is the term "thirst trap" that eludes him.

Meanwhile, I freely admit I'm still entirely in the dark.
