In March, Kendrick Lamar dropped "The Heart Part 4," a lyrical onslaught in which he seemed to target an unnamed rapper, spitting the following bars:

"My fans can't wait for me to son your punk ass and crush your whole lil shit
I'll Big Pun your punk ass you a scared lil bitch
Tip-toeing around my name n***a you lame
And when I get at you homie don't you just tell me you was just playin
'I was just playing K-Dot, c'mon you know a n***a rock with you bro'
Shut the fuck up you sound like the last n***a I know
Might end up like the last n***a I know
Oh you don't want to clash? Yeah n***a I know"

Fans immediately speculated that Kendrick was targeting Big Sean, after the Detroit emcee reportedly fired off some subs of his own on DJ Khaled's "Holy Key." Afterward, the narrative became accepted, and while Sean and Kendrick never said each other's name, people were quick to wonder if either one would ever come through with a full-on diss track. As of today, that moment has yet to come, but it seems as if Big Sean isn't quite ready to let Kendrick have the last word.

Today, Metro Boomin and Big Sean delivered their collaboration album Double Or Nothin, and both fans and Complex were quick to note a few lines on the album's second track "Big Bidness." In the track's closing bars, Big Sean spits the following:

"Nobody sonning me
If am a sun, I'm the one you look up to
Fuck you" 

After all, Kendrick did threaten to "son" a rapper who may-or-may-not be Big Sean. Either way, both parties seem content to fire off a few subliminals a year, so perhaps we'll hear Kendrick issue a veiled response at some point in 2018. What do ya'll think? Is Big Sean really responding to "The Heart Part 4?" And if so, who are you backing in this beef?
