But just confuse me with my pa because I am the Birdman J.R
I ain't trippin' nigga,

from Lil Wayne – BM J.R. Lyrics on Rap Genius

Meaning

Simple: The rapper ‘Birdman’ (one-half of Cash Money Records) is a sort of surrogate Father for Weezy, who’s paternal Father is long dead. His career owes a lot to Baby (Birdman,) so he doesn’t mind saying ‘don’t confuse me with the law, naw, just confuse me with my Pa because I am the Birdman J.R.’

‘I ain’t trippin’ is a constant sentiment for rap centered around a more street lifestyle. Now used to describe erratic behavior in general, ‘trippin’ is a blanket-term for total sensory disorientation, usually because of a psycho-active drug.
By saying this, he is clarifying that none of his actions are out of his control; that he is capable and is always giving a representation of how he feels.
