Hugh Jackman acting out 'go with the flow' during Catchphrase is everything

Warning: There's a part of this guessing game that gets a little NSFW. 

On Monday night, Eddie the Eagle stars Hugh Jackman and Taron Egerton played a game of Catchphrase with Jimmy Fallon and Steve Higgins on The Tonight Show.

Egerton and Jackman appeared to be worthy opponents for the late night host and his announcer until Jackman got the phrase "go with the flow," and Egerton was completely mystified.

At about the 4:10 mark, Jackman began:

"We're gonna relax, and I want you to just..."

Then, he started moving his limbs with very fluid motion, but how he moved them made Egerton think the phrase was far more sexual than it actually was. (Get your mind out of the gutter, Egerton. This isn't Family Feud here!) After about 30 seconds, the buzzer went off signaling that Higgins and Fallon were victorious, and Egerton was left wondering:

"What the hell was it?"
