Kendrick Lamar Fan I Got Screwed Out of Meet & Greet ... GIMME $1 MIL!!

1207-kendrick-lamar-TMZ-01A die-hard Kendrick Lamar fan paid $350 for a backstage meeting, but got banned from the concert after Kendrick's manager tried to bamboozle her for $10,000 ... according to a lawsuit. 

Whitney Larkins says she emailed Lamar's manager, Dave Free, asking for 3 minutes of one-on-one time with Lamar ... on top of the $350 VIP meet and greet package she'd purchased. In a lawsuit she filed on her own, Larkins says Free replied she could get the 3 minutes for a "cash payment of $10,000."

The figure didn't scare her off because Larkins says she repeatedly tried to get more info from Lamar's team, which apparently ticked off someone. Larkins says she got an email the night before the concert saying she was banned, and would get her $350 refunded. 

Larkins isn't pissed at Lamar, in fact she calls him "one of the greatest rappers alive of all time who is on par with Tupac." But she says Free crushed her dreams and left her with "deep sadness" -- and wants more than $1 million to make it go away.

And the best lawsuit line ever -- she calls Free an "arrogant, snotty and an all-around bad dude from the rooter to the tooter!" 

We reached out to Free for comment. No word back.
