Kourtney Kardashian is celebrating her 38th birthday with her gal pals on the beaches of Tulum, Mexico, and if her sister Kim Kardashian's photos and live-tweets from the party are any indication, things are getting pretty crazy.
Kim took to Twitter on Monday, where she shared a lot from their vacay, giving fans a "play by play" of the trip. And we mean, she shared a lot.

"@kourtneykardash threw up in her bed 4 times and slept in it," Kim wrote in a lengthy series of tweets.
"@BrittGastineau skinny dipped solo and then disappeared for the two days," she continued. "@larsapippen tried to give me a "special" brownie and I threatened to sue her & the chef."
Other revelations include: "I put nipple clamps on @ForeverMalika" and "@kourtneykardash won't stop doing naked cart wheels."

Kim also made sure to share some photos from the wild night, posting to both Twitter and Snapchat. The photos commemorated the elegance of the evening's festivities -- like when the friends all posed for photos with a giant inflatable penis.
Or this video of Kim's friend Sarah Howard twerking, which Kim apparently didn't think was good enough.

There was also a whole subplot about Kim's fight with her stylist, Jen Atkin, over the unhealthiness of an Oreo milkshake.
"@jenatkinhair spiked my Oreo shake to try to get me to not eat it because she's fat shaming me," Kim wrote.
However, she later posted a video of herself enjoying an tasty shake, which she tagged, "#F**kYouJenAtkin."
Although it seems Jen ultimately enjoyed the shake as well. Kim seemingly forced her friend to admit, "The Oreo shake was worth it."
