Lamar Odom is getting the rap treatment ... thanks to a rapper on Rick Ross' record label who just dropped a new song inspired by L.O. ... and it's littered with some serious crack undertones.
The guy behind the song is Whole Slab -- a member of Rick's Maybach Music Group -- and his new single "Lamar Odom" is all about smokin' something called "Lamar Odom."
Slab tells TMZ Sports straight up ... "Lamar Odom is now the street word for that illegal white substance."
Clearly, the lyrics were inspired by Lamar's substance abuse issues -- particularly, his issues with crack.
As for Rick Ross' role on the song -- Slab says, "Rick inspired me and guided me through the making of my album. Lamar Odom is my first single and we're going to shoot a video for it."
