Chief Keef Kicked Out of Home -- I Was Evicted Because 'I'm Too Bad!'

Chief Keef says back rent was not the trigger for his eviction ... he tells us he was booted from his apartment because his neighbors just didn't like him.

TMZ previously reported ... Keef was evicted from his unit in Highland Park, Illinois Tuesday. Sheriff's deputies escorted him out, and there were reports he owed $11,300 in back rent.

But our photog spotted a self-professed "turnt up" Keef in West Hollywood hours after the eviction ... and he says it's not about money ... it's because, "I'm too bad, I guess I'm a bad little young boy, I gotta go."

Here's what's clear from the video ... Keef isn't stressing.
