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.
