Belek is a slang term in French, particularly common in urban youth language, meaning "watch out" or "be careful". It's derived from Arabic and is a unique, less common word in mainstream French vocabulary.
In the song, the artist uses Belek to warn others to be cautious when speaking to him, emphasizing his street credibility and the potential consequences of disrespect. It adds a raw, authentic edge to the lyrics, reflecting the artist's background as a "ghetto boy".
GTB is Jey Brownie's proud, gritty self-portrait as a 'ghetto boy' who built his life the hard way. He credits his mother's smile as his greatest joy while describing the hustle and street risks that shaped him.
He turns sharp on people who only show up for money or fame, warning a woman who wanted his cash that there's no future between them, and cautioning rivals not to test him now that the tables have turned.
The second half leans into swagger: comparing himself to Tupac's 'All Eyes On Me,' rejecting anyone trying to control his lifestyle, and insisting his success is real, not a game he's playing.
