We all know that AKA made that "unlock the world" term, right?

The award-winning rapper has been at it for months, using the phrase in his social media updates. 

So, this seems to have inspired Avis' latest advertisement campaign. The rapper, who is clearly not impressed (we totally understand), took to Twitter to share his feelings about this.

He tweeted the company, and described this as "just shocking".

Brands and agencies have hi jacked terms that we've coined many times before. It's not the 1st time.

The Major League DJz also shared their thoughts.

This really pisses me off...They keep doing it https://t.co/irbtr5pqEG

They asked AKA what can be done to stop this from happening. His response was: "I don't know, we have to figure something out. Surely won't be the last time."

Back in February, Cassper Nyovest also took to Twitter to air his frustrations about SuperSport. The sports channel used Slyza Tsotsi in a promo, a song that features Cassper, without the owners' permission. He tweeted: "SuperSport 4 using Slyza Tsotis slogan. Are we getting paid? Nope. Just like when Savanna used my sh**. Corporates never loved us." 

Last year, the alcohol brand angered Cassper after using his hit track Doc Shebeleza in an advert. The ad had used the lines "Dark... Dark Shebeleza" without consulting the rapper and his management.
