Last night, World of Dance entered into the Duels round, where dancers competed head-to-head within their divisions to see who will move on to the next round, the Cut. While the night was full of surprises, one of the biggest upsets came in the first duel between high-scoring trio Tobias and the EZ Twins versus the underdogs, the D'Angelo brothers.

The Italian tap dancing brothers blew everyone away with an impressive performance to "Tutti Frutti." Judge Jennifer Lopez even said it was the first time shed gotten "goosies" during a tap routine. (The D'Angelo brothers won their duel, btw, proving everyone really does love an underdog story.)

In case you missed it, check out their goosie-inducing routine:

But wait, what are "goosies," exactly?

If you guessed its J.Lo's (ridiculously adorable) nickname for "goosebumps," youd be right. In fact, "I got goosies" is one of J.Los trademark comments on the show, and its definitely a compliment every time. (Another recent performance that left J.Lo covered in goosies was contemporary soloist Lauren Yakimas routine to "I Just Died In Your Arms Tonight.")

J.Los signature remark actually stems from her days as a judge on American Idol, where she explained that she usually gets goosebumps on her arms and legs, but sometimes, all the way up to her face when someone really slays their performance.

In case youre wondering, the other judges are totally on board with sharing when theyve been hit with the goosies as well. Earlier this season, Derek Hough praised 10-member group Unity L.A.s contemporary performance , declaring, "I got goosies on my thighs."

And if last night's episode is any indication, there will be plenty of goosies in season 3.
