At this point, the Jenelle Evans-Kailyn Lowry feud has been going on so long that it's easy to forget they were once friends.
But believe it or not, there was a time when the Teen Mom 2 co-stars were thick as thieves.
Which is fitting, since Jenelle has an arrest record about as long as that of a career criminal.
The Carolina Hurricane has been taken into custody so many times that we're guessing even she's lost count.
But there's one arrest that very much remains on the mind of Jenelle's biggest rival, and she took to Twitter to talk about it over the weekend.
"Do y'all remember the time I gave Jenelle money to make bail?" Kailyn tweeted.
She then dropped a phrase that she's adopted as her unofficial motto:
"Before you throw dirt on my name remind them how hard you f-cked [with] me."
The incident Kailyn is referring to took place in 2011 when Jenelle was arrested for probation violation.
Lowry apparently lent Evans $150 to cover the cost of bail.
Not a ton of cash, but this was before the girls were as rich as they are now.
Needless to say, the comments on Kail's tweet were very interesting.
At one point, Jenelle's troubled ex Courtland Rogers weighed in with what first seemed like trash talk, but later appeared to be words of support:
"I remember the time u called her a bitch to her face in New York that time behind the stage at dr drew reunion and she froze up and was scared to death of u but kail what u don't kno is that when u went on stage all she did was talk mad shit about u! she ain't s--t don’t stress," Rogers tweeted.
You know the drama is real when even the tweets have plot twists.
Jenelle and Kail's mutual hatred has ebbed and flowed over the years, and it seems to have spiked recently when Evans sent cease and desist letters to several of her co-stars, including Lowry.
It's unclear what prompted Kail's seemingly unprovoked tweet on Saturday.
It's possible she was just sitting around contemplating how much she dislikes Jenelle, which frankly, is one of our favorite weekend activities.
