Jennifer Lopez doesn't always come out on top. In fact, last night, she was on the bottom.

The Boy Next Door actress teamed up with Jimmy Fallon to play three rounds of Catchphrase on NBC's The Tonight Show. They played against actor Anthony Mackie and the show's announcer, Steve Higgins.

"Dude! I don't like to lose!" Lopez warned her teammate.

Mackie was equally competitive, saying, "I had to get rid of Taboo in my house. I start fights!"

During the intense first round, the teams' phrases included "Super Bowl," "photobomb," "ugly duckling," "fist bump," "hump day," "make it rain" and "slow your roll." Lopez and Fallon took the early lead after the buzzer sounded during Mackie's turn, and it took all four players a minute to recover for round two!

"Oh, my God!" Fallon said. "That was the best round of the game I've ever played in my lifetime!"

The second round of phrases included "hula hoop," "couch potato," "pinkeye," "tough cookie" and "tongue-tied." Lopez tried to describe "chip on your shoulder," but the buzzer went off just before Fallon figured it out. "Go back to the tape!" the host argued. Lopez reminded him, "There's no replay!"

For the third and final round—the tie-breaker—the competitors described the phrases "five o'clock shadow," "in the doghouse," "funny bone" and "wisdom teeth." Lopez's card read "bottom line," and she tried her best to clue Fallon in. At one point, she pointed to her butt. "The rear!" the comic shouted.

Needless to say, they lost.

"I'm so mad! I'm so mad!" Lopez said. "I hate you!"

Fallon laughed and replied, "I was distracted!"

Earlier in the episode, Lopez explained how her mom won $2.4 million. Watch the clip to find out how!
