Stop us if you've heard this before, but ...
... Javi Marroquin has some very negative things to say about Kailyn Lowry.
The ex-husband of this Teen Mom 2 veteran took to Twitter on Friday and laid the proverbial smackdown on the mother of his son, blasting Lowry in a series of harsh messages.
What prompted this outburst? It's unclear.
What did Javi say about Kailyn?

Teen Mom 2 cast member Kailyn and Javi are divorced. They share a son named Lincoln and have each accused the other of infidelity before, during and after their separation.
Recent rumors surrounding Javi have had more to do with Briana DeJesus than with Kailyn, as Marroquin and this other Teen Mom 2 star are apparently dating ... and getting hot and heavy.
Kailyn is Always Around, Though
Even while she celebrated her love for Javi, Briana recently Tweeted "#yeaididwin," what many felt was a clear reference to somehow coming out on top over Lowry in the battle for Javi's heart. There's clearly tension between all involved here.
Lowry Fires Back
In response to Briana's claim that she "won," Kailyn tweeted a few of the emojis where the little face is laughing so hard it's crying ... vague enough, but her followers assumed she was talking about Briana's photos. Team Kail began making many jokes at her rival's expense, and Lowry tweeted, "Lmaooooo y’all picking up What I’m laying down i see," implying that their instincts were on point.
In particular, someone tried to speculate on what Briana thinks she won, writing "She won the lowest paid Teen Mom salary." Rather than letting that slide, Kailyn responded with "Bruh 😂😂😂😂😂😂😂😂 #petty" Indeed. And things only escalated from there.
Lowry then wrote "#iwon more time with my son," which is possibly the best comeback anybody could have written to anyone about anything. As you can imagine, this led to some major tension with Javi and Bri.
