Remember the glory days of Teen Mom 2 when Kieffer Delp and Jenelle Evans were still dating? We'll never forget the fated moment that these two met, when Kieffer uttered the glorious pick up like "Ya’ll sure ya’ll fine?" He then took Jenelle on the most magical first date of her life — to a local alligator swamp. Jenelle and Kieffer's relationship only evolved from there, with several makeout sessions in the booths of Planet Fun, as well as some dangerous flirtations with theft and homelessness. Good times!

But Jenelle and Kieffer just weren't meant to be, which Jenelle realized after Keef enabled her addiction to heroin. These two haven't seen each other since their drug-fueled breakup, but they're still in each other's lives thanks to a little somethin' somethin' called Twitter.

Despite the fact that Jenelle and The Delp have moved on (she's pregnant with another man's baby, after all), they find time in their busy schedules to subtweet each other. Case in point, a recent musing from Kieffer in which he tweeted the poetic "If I downgraded I'm outta verses and the Hurst is outta trunk space #neverdat."

Not quite sure what this means, but Jenelle is officially offended, and took it to Twitter to throw some shade. "Assuming makes an ass out of u and me now doesn't it?" she tweeted to her ex-boyfriend. "Thought u knew that."

Stick that in your hand-whittled pipe and smoke it, Kieffer. Oh wait, you can't because Jenelle confiscated all your pipe-carving tools. Awkward!

Do you think Jenelle and Kieffer should leave the past in the past and move on with their lives, or do you understand why she felt the need to put him in his place? Weigh in below.
