They say, "K, you going marry mines
Beeotch no way, beeotch no way
Beeotch no way, beeotch

from Kendrick Lamar – Backseat Freestyle Lyrics on Rap Genius

Meaning

Kendrick runs into a problem that many talented rappers face: the women who want to marry him in the midst of his ascension to greatness (and probably profit from his success in a later divorce action.) He knows better, though: just say no to gold diggers.

The bouquet in the previous line is thrown by the wife at weddings.

This line might also be an explanation as to why Sheranes cousins/brothers jump Kendrick later on in the album. They see Kendrick as just another guy trying to get it in, then get out.
