Don't ever fix your lips like collagen
And say something when you gon' end up apologing
Throughout the song, Kanye has been intertwining a nice parallel between the hypocrisy of poor ghetto culture, and his own hypocrisy. He is always saying things he ends up regretting, so he is talking about his own faults too
Collagen injections are used for cosmetic lip surgery
Note that Kanye is over-emphasizing words (and even making ones up (apologing)) to get his desired rhyme scheme, relating the two lines above.
Basically, don’t ever open your mouth to say something you’ll later regret. Like when Kanye said “George Bush doesnt care about black people”, which he later ended up apologizing for.
