From an instagram post by Dee-1 below
The @lupefiasco Effect: when we did the #AgainstUSRemix he cursed on purpose on his verse to see if i would 1. keep it because he's my friend and bc of me not wanting to create an awkward moment in the studio with us or 2. stay true to my brand and bring it up to him/take it out. ? little mind games that keep me sharp. This was done bc speaking up was something i shared with Lu that i had struggled with in the past. I'm thankful for homie. — #AgainstUSRemix music video coming soon! Dee-1 x Lupe x Big Krit ???
During the Interview, Dee-1 said “When I asked Lupe Fiasco to hop on my song, he was totally cool with it… He knows that I don’t curse and that I don’t have profanity in my music. On the last bar, he said “My kind and they logic is like 99 of their problems with no B… I’m like Oh boy, here we go [laughs]. Do I speak up and create this awkward moment in the studio or do I let it ride? I decided to speak up and we had a little conversation about it and he was cool with removing it…”
Dee-1 also mentioned that Lupe, while talking with someone else, said “He don’t know it, but I cursed on his record on purpose just to see what he would do.”
It would appear that Dee-1 was being tested by Lupe and we can say that he passed with flying colours. As always Dee-1 rocks the unashamed banner with pride by being Real, Righteous and Relevant.
