“Joy Ride” is loud, vulgar and crude, exactly what you’d expect from an Asian-American romp across “Girls’ Trip/Bridesmaids” terrain.

But “Crazy Rich Asians” screenwriter turned director Adele Lim gives this raunchy road trip comedy a “Joy Luck Club” detour into sentiment that sets her directing debut apart from all the other “women gone wild” outings of recent vintage.

It’s an unfiltered farce about growing up as “the Asian kid” in America, and about the adoptions end of the Chinese-American diaspora, a comedy of life paths and high expectations, finding your roots and having a lot of noisy, stereotype-smashing mishaps along the way.

Lim delivers a film littered with “Oh no they DIDN’Ts,” one that leans into the culture and swats the image in a lot of profane and unexpected ways.

Audrey was adopted by a white American family as a child. Luckily for her, the tiny bit of white suburbia where she moved already had a Chinese girl, Lolo, who’d moved there with her family.

When an elementary schooler trots out that favorite Asian slur of the underage and ignorant, Lolo’s response is profane and appropriately pugilistic.

A lifelong bond is born.

Years later, Audrey (Ashley Park of “Mr. Malcolm’s List”) is a rising star corporate attorney ready to close the Big China Deal. Lolo (comic and actress Sherry Cola of TV’s “Good Trouble” and “I Love Dick”) rents her garage apartment and makes genitalia-inspired art, bless her heart.

But if Audrey is going to China, she’ll need somebody with a slightly better handle on the language, as Audrey grew up with white parents. Lolo it is!

They’ll fly over, indulge in the Chinese rituals that accompany business deals (binge drinking, karaoke, slap-fight games). Audrey will catch up with her college roommate Kat (Oscar nominee Stephanie Hsu, who’s in everything, and was in “Everything Everywhere All at Once”) who is now a famous Americanized actress in Chinese cinema and TV.

And danged if that cousin-we-all-avoid doesn’t tag along on the trip. “Deadeye” (Sabrina Wu, making a deadpan screen debut) came by her nickname honestly, and it has nothing to do with marksmanship.

Business with the Chinese would-be client, a little sight-seeing, a little catching up with Deadeye’s family. Maybe they’ll even, you know, try and track down Audrey’s birth mother.

Their odyssey will bring a “best friends” rivalry (Lolo vs. Kat) to a boil, Asian “identity” into the spotlight and business to a halt as this motley quartet makes its way across China. The complications include family matters and love interest(s), drug smuggling and basketball, some of which land harder than others.

Lim finds her biggest laughs on the heels of every “Aww, isn’t that...” moment, starting from shy Audrey and brash Lolo meeting as tiny tykes.

Audrey finds a nice, safe “American” blonde (Meredith Hagner of “Search Party”) for them to share a train car with, and then the cops show up looking for a drug smuggler. The blonde panics and implicates one and all by blowing cocaine on everyone.

“You’re drug dealers NOW, bitches!”

The B-word is generously deployed throughout as mishap piles on top of mishap, Kat keeps getting recognized as the star that she is and Lolo uses every opportunity to try out her Mandarin vulgarisms and international gestures deploying her tongue and fingers to shock and awe the People’s Republicans.

Seth Rogen is one of the producers here, and the “best joke on the set” ethos infests this movie — shock-value profanities, throw away lines about racist “Mulan-themed office parties” and the Americans marveling how “We look like everyone else, for once” land laugh after laugh.

Hsu shows a sharp edge here, with Park letting us see a more outrageous side and Wu doing well with that always underestimated “nerdy, quiet one” type. But Cola fizzes and sizzles and swaggers through every scene, a bawdy force of nature, the Asian Danny McBride in this Rogenesque Lim China shop.

But the picture peaks, and nobody involved could think of a graceful way to finish during a turn toward the serious. Whatever one gets out of the third act, we can all hear what the director and screenwriters were muttering off camera in these scenes.

“How do we get out of this?”

Because once you’ve delivered your big “cocaine” joke, and played your “pose as K-pop stars” cards, what else is there?

But “Joy Ride” still fulfills the R-rated promise of “Crazy Rich Asians,” an outrageous comedy that isn’t just about representation. It’s a reminder that rude, raunchy laughs travel, translate and tickle, no matter who you are and where you’re watching.
