Even Liam Hemsworth can't keep up with all of the slang surrounding social media.
The 29-year-old actor had to Google the term "thirst trap" after his "Isn't It Romantic" co-star Adam Devine commented on a recent Instagram photo using the term.
The post contained a black-and-white photo of Hemsworth with his dog, taken by the actor's brother Luke.
"@hemsworthluke captured this moment of me and my best friend Dora. Good god I love this dog," Hemsworth said in the caption.
Devine, 36, commented with, "thirst TRAP."
"I just googled thirst trap. 100% true,” Hemsworth responded.
The two were first spotted together in October, just weeks after Cyrus, 27, began a romance with singer Cody Simpson.
